Embodiment

In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.

The task number that the embodiment of the present invention is included by inquiring about at predetermined intervals in waiting task storehouse, and root Current thread is adjusted in real time according to the task number and starts number, so that the service response ability of terminal device is waited to locate with current The quantity of reason task matches；Terminal device is after determining that thread starts number, then from waiting task storehouse, based on each The priority of waiting task, the extraction waiting task consistent with thread startup number from waiting task storehouse, and carry out Response, it is achieved thereby that the thread of dynamic adjustment terminal device starts the purpose of number, solve the method for adjustment of existing thread, The quantity of thread is changeless, if in heavy traffic period, the thread of startup possibly can not meet current portfolio, from And cause waiting task to overstock, so as to reduce the efficiency of service response, substantial amounts of task failure or time-out are even resulted in, drop The problem of service quality of low server and the usage experience of user.

In embodiments of the present invention, the executive agent of flow is the terminal device for being provided with thread adjustment programme, and terminal is set Standby to include the terminals such as mobile phone, computer equipment, tablet personal computer, especially, the terminal device is specially a server, for receiving The service request of each user terminal initiation is simultaneously responded, and response results then are returned into corresponding user terminal, so as to Realize the operation of service response.Fig. 1 shows the implementation process figure of the method for adjustment for the thread that first embodiment of the invention provides, Details are as follows：

In S101, the task number that includes is inquired about in waiting task storehouse at predetermined intervals.

In the present embodiment, terminal device then appoints processing after the processing task of other users terminal transmission is received In business storage and waiting task storehouse, when machine reaches when treated, according to the priority of each waiting task and to connect Order is received, corresponding waiting task is extracted and is responded.

It should be noted that the waiting task storehouse can be in the local storage of terminal device, and in this case, terminal Equipment directly reads local storage, you can obtains the relevant information of waiting task；Waiting task storehouse can also be one only Vertical storage server, specially receive and store the processing task that each user terminal is sent.Because terminal device needs simultaneously The processing task that multiple user terminals are sent is responded, that is, needs to distribute certain port number, to perform the reception of processing task Operation, on the other hand, terminal device also need result returning to user's end after waiting task corresponding to response completion End, now, return to operation needs to call certain port number again.Therefore, terminal device is in order to improve the effect of its service response Rate, an independent storage server can will be set, the port of respective numbers is set, the processing that other users terminal is sent is received and appoint Business, terminal device only needed between waiting task storehouse, establish a data link be used for obtain needs waiting task i.e. Can, other ports can be used for the result of generation feeding back to user terminal.

In the present embodiment, terminal device inquires about in waiting task storehouse the task included at predetermined intervals Number, wherein, the default time interval is specially the task extracting cycle of terminal device.There is terminal device default task to carry Cycle and task response cycle are taken, terminal device will extract phase when reaching task extracting cycle from waiting task storehouse The waiting task of quantity is answered, and enters task response cycle.In task response cycle, terminal device passes through multiple threads pair The waiting task of extraction is responded, and can't extract waiting task from waiting task storehouse, and week is responded in task After phase, if arriving again at start-up time corresponding to task extracting cycle, circulation performs the operation of extraction waiting task. And the step of S101 of the present embodiment offer, then enters the operation performed during task extracting cycle for terminal device.Illustratively, Such as default time interval is 2 minutes, then terminal device will inquire about in waiting task storehouse including for task in every two minutes Number, then the task in the waiting task storehouse is responded.Certainly, the duration of default time interval can be according to user Actual demand be configured, such as 30 seconds, 10 minutes etc., whether rush hour section can also be belonged to according to current slot, Adjust the default time interval.

Alternatively, in the present embodiment, also include before S101：Pass through default waiting task checking algorithm, school The legitimacy and integrality of waiting task are tested, if verifying successfully, is stored in waiting task storehouse, and perform S101 phase Close operation；Conversely, if verification failure, abandons the task requests, and return to the illegal information of task and be given to corresponding user's end End.By above-mentioned means, terminal device can pre-process to waiting task before treatment, most of illegal so as to filter out Task, not only reduce the service response pressure of terminal device, moreover it is possible to discharge the memory space in more waiting task storehouses, be used for Preserve other effective waiting tasks.

In S102, the upper limit is started according to the task number and default thread, it is determined that current thread startup Number.

In the present embodiment, terminal device then obtains pre- after the task number included in obtaining waiting task storehouse If thread start the upper limit, judge that task number and thread start the size of both upper limits, determine whether can be each Individual waiting task distributes an independent thread and responded.If task number, which is less than or equal to thread, starts the upper limit, table Show can be that each waiting task sets a thread, to respond above-mentioned waiting task, now current thread starts Number is task number；Conversely, if task number, which is more than default thread, starts the upper limit, then it represents that can not be the quantity of task More than openable number of threads, i.e., in this subtask response cycle, the waiting task of whole can not be responded, therefore The thread startup upper limit is arranged to current thread and starts number.

Alternatively, in the present embodiment, terminal device can also be that thread corresponding to each task type is set starts The upper limit.In this case, terminal device not only obtains the task number included in pending task library in S101, always according to respectively Task number corresponding to each task type is counted, then opens the task number of each task type with corresponding thread The dynamic upper limit is compared, and obtains the thread promoter number of each task type, so as to pass through multiple thread promoter numbers Calculate current thread and start number.Terminal device is in order in every subtask response cycle, except response priority is higher Task outside, certain resource has also been reserved to respond the relatively low task of priority, so as to avoid the relatively low task of priority Type is delayed execution always, thus for each task type set corresponding to thread start the upper limit, so as to it is balanced each The number of responses of task type.

Illustratively, terminal device is net recommendation server, the net recommendation sent for responding each user terminal Service request, the wherein net recommendation service request include but is not limited to：Influence clothes of the user to the net recommendation of interactive object Business, such as online service consulting, suggestion feedback reply, failure declare processing, are also included within and calculate the net recommendation mistake of interactive object Respective service request in journey, such as sample operations feedback opinion collection service request, sample operations feedback opinion sends service please Ask.Because net recommendation service request typically has stronger real-time, therefore, wait to locate when net recommendation server detects Net recommendation service request is included in reason task library, then can preferentially be handled.If in some period, net recommendation server Substantial amounts of net recommendation service request is persistently obtained, and because the priority of the service request is higher, server is at each Net recommendation service request is only responded in business response cycle, then other service requests can be caused to cannot respond to.Therefore, net recommendation Server starts the upper limit, such as the net recommendation service for entirety for thread corresponding to different service request type settings Device, it is 100 that its thread, which starts the upper limit, and it is 80 that thread corresponding to net recommendation service request, which starts the upper limit, other kinds of clothes It is 20 that the thread of business request, which starts the upper limit,.It can be seen that server ensure preferentially to respond net recommendation service request it is same When, certain threading service has been reserved to respond other kinds of service request, so as to reasonably distribute Service Source.

Preferably for such scheme, the task number of the first kind is less than corresponding thread and starts the upper limit, and The task number of Second Type is more than corresponding thread and starts the upper limit, now, the remaining line of task number of the first kind Journey, the task available for response Second Type.Illustrative, the task number of the first kind is 15, and its corresponding first thread Start the upper limit be 30, therefore, terminal device distribute to the task of the first kind resource there remains 15 threads will be in sky In the spare time, other kinds of task can be responded.Now, terminal device determines that the task number of Second Type is 25, and its corresponding second It is 20 that thread, which starts the upper limit, therefore in remaining 15 threads in the thread of the first kind, can will extract 5 threads and be used to respond The task of Second Type, so as to according to actual conditions, rationally call the resource of each type.

In S103, based on the priority of each waiting task, extraction and the line from the waiting task storehouse The waiting task of Cheng Qidong numbers matching.

In the present embodiment, terminal device obtains the priority of each waiting task first, and according to true in S102 Fixed current startup number of threads N, N number of waiting task of highest priority is extracted from waiting task storehouse, be used as this The waiting task that subtask responding process performs.

In the present embodiment, the priority of waiting task can be entered by task initiator by the user of task requests Row is set, and user is when generate waiting task, then the priority of setting waiting task, so that terminal device is treated receiving During processing task, its corresponding priority can be based on, it is determined that corresponding response opportunity.Specifically, user directly sets priority Parameter, such as priority byte in waiting task, set corresponding parameter value；Can also be by limiting task feedback time Mode, the priority of waiting task is set indirectly, such as the higher waiting task of priority, it is corresponding predetermined anti- It is shorter to present the time；And the relatively low waiting task of priority is corresponded to, its corresponding feedback on reservation time is longer.

In the present embodiment, the priority of waiting task can also be configured by terminal device.Specifically, terminal is set The standby task type according to waiting task, default task type and priority corresponding relations list are inquired about, so that it is determined that treating The priority of processing task, and generate the corresponding relation list of waiting task and priority.Terminal device is performing S103's During operation, then the corresponding relation list of the waiting task and priority is directly read, you can determine each waiting task pair Answer priority.Preferably, the waiting task in the corresponding relation list of waiting task and priority, according to the big of priority Small order, is ranked up successively, if priority identical waiting task, the sequencing that the time is obtained according to task is carried out Sequence, so as to which terminal device directly intercepts waiting task corresponding with thread startup number N, without obtaining priority letter one by one After breath, then extracted, improve task response efficiency.

In S104, start thread corresponding with thread startup number, and by waiting to locate described in thread response Reason task.

In the present embodiment, terminal device starts number according to the thread determined in S102, starts corresponding quantity Thread, and the thread by having been turned on responds the waiting task for extracting to obtain in S103.Specifically, each thread responds One waiting task, so as to realize purpose that multiple waiting tasks concurrently respond.

In the present embodiment, after a certain thread of terminal device has completed a waiting task, then obtain corresponding to the task User's mark is asked, and is identified according to request user, task result is fed back to corresponding to request user mark eventually End.Wherein, the operation of result feedback can transfer to the thread for responding the waiting task to perform, and can also have been performed in thread Into after task, the network address of result and counterpart terminal is sent to result sending module, transfers to result Sending module uniformly carries out the transmission operation of task result.

Alternatively, in the present embodiment, terminal device can collect the result of all thread generations of this response cycle Afterwards, just unify result feeding back to corresponding user terminal.In this case, because some waiting tasks may relate to And data operation quantity it is less, therefore the thread for handling the waiting task of the type can more early complete response operation, and locate It is uniformly to be transmitted to manage result, i.e., above-mentioned thread is in idle condition.In this case, terminal device can arrange the free time Thread supports the slower thread of progress, i.e., by two threads while the slower waiting task of implementation progress, so as to comparatively fast appoint The speed of response of business and the utilization rate of resource.

Above as can be seen that a kind of method of adjustment of thread provided in an embodiment of the present invention passes through at predetermined intervals The task number included in inquiry waiting task storehouse, and current thread is adjusted according to the task number in real time and starts number, So that the service response ability and the quantity of current waiting task of terminal device match；Terminal device is determining thread After starting number, then from waiting task storehouse, based on the priority of each waiting task, extracted from waiting task storehouse The waiting task consistent with thread startup number, and responded, it is achieved thereby that the thread of dynamic adjustment terminal device opens The purpose of dynamic number.Compared with existing service response technology, the startup number of threads of server keeps constant, when pending When being engaged in less, easily there is thread startup but free time, waste the resource of server, when waiting task is more, again will not Increase the number that current thread starts, easily cause the overstocked situation of task, and the present embodiment is every time to waiting task Before concurrently respond in batches, by according to the waiting task included in currently pending task library, current thread is adjusted Start number, so as at the time of reaching in each service response cycle, keep the service response ability of terminal device with currently Number of tasks matches, and improves the efficiency of service response and the service quality of terminal device, provides the user more preferable use Experience.

Fig. 2 shows a kind of method of adjustment S102 for thread that second embodiment of the invention provides specific implementation flow Figure.Shown in Figure 2, relative to embodiment described in Fig. 1, a kind of method of adjustment S102 for thread that the present embodiment provides also includes Following steps, details are as follows：

Further, it is described that the upper limit is started according to the task number and default thread, it is determined that current thread opens Dynamic number, including：

In S201, the temporal information at current time is obtained.

In the present embodiment, the default thread startup upper limit changes with time and changed in terminal device, i.e., not Same period, corresponding thread start the upper limit.For example, for free time section, terminal device average received is waited to locate Reason task quantity is typically less, and now, terminal device need not be operated in full load condition, but can be progressively to pending Task is responded, therefore the thread startup upper limit is smaller；Conversely, in peak hours/period, terminal device largely treats lasting reception Processing task, now, terminal device can be at full load condition, avoids waiting task bulk deposition and causes batch tasks to be lost Effect.

In the present embodiment, terminal device, will be true after the task number included during currently pending task library is determined Determine the temporal information at current time.Wherein, the temporal information can be absolute temporal information, such as 18:53, uniquely determine current Time；The temporal information can also be relative temporal information, such as the duration of terminal device operation, the duration of fully loaded pattern For representing the temporal information of terminal device running status.In this case, terminal device defines each operational mode most Big run time, if the run time of the temporal information at current time, i.e. operational mode is more than maximum run time, then switch The operational mode of the terminal device, and correspondingly adjust current thread and start the upper limit, so as to which keeper passes through configuration response Operational mode starts upper limit relation list with thread, then the thread that can adjust terminal device in real time starts the upper limit.

In S202, start the corresponding relation of the upper limit and temporal information based on default thread, determine the temporal information The corresponding thread starts the upper limit.

In the present embodiment, terminal device is previously stored with the thread startup upper limit corresponding to each different temporal information, And generate the corresponding relation that thread starts the upper limit and temporal information.Wherein, the corresponding relation can be from the upper clothes of terminal device Obtained in business device, the upper server determines each equipment in different time by obtaining the running situation of multiple terminal devices Thread starts the upper limit corresponding to section, then generates the general thread for being applied to an each terminal device startup and reaches the standard grade and believes with the time The corresponding relation of breath.Therefore, each terminal device can directly obtain the corresponding relation from upper server, and store and local Memory module in.

In the present embodiment, user can generate the thread and start the upper limit and temporal information according to the use demand of reality Corresponding relation, it can also be adjusted based on existing corresponding relation.For the ease of management, terminal device sets so as to system default The corresponding relation that the thread starts the upper limit and temporal information is generated outside the mode put, user can also be allowed to be generated or adjusted.

Terminal device will inquire about default the thread startup upper limit and temporal information after current temporal information is determined Corresponding relation, determine that current time corresponds to thread and starts the upper limit, then perform S203 associative operation.

In S203, the thread starts the upper limit according to corresponding to the task number and the temporal information, it is determined that Current thread starts number.

In the present embodiment, terminal device will be waited to hold after being determined that thread corresponding to current time information starts the upper limit Compared with the task number included in row task library and thread start the upper limit, above-mentioned less numerical value in both is chosen as working as Preceding thread starts number.

In embodiments of the present invention, the numerical value of the thread startup upper limit is not changeless, but can be according to different Temporal information is adjusted, and so as to effectively utilize the thread resources of terminal device, is avoided the unnecessary wasting of resources, is improved The utilization ratio of resource, and the flexibility of terminal device.Especially, terminal device may be for a long time in full in peak hours/period It is operated under load or the pattern of overload, therefore in order to provide terminal device certain phase buffer, it is whole in non-rush hour section End equipment may be at loading it is less in the state of work.For example, a certain task extracting cycle between at one's leisure, terminal device Detect and 100 waiting tasks are included in waiting task storehouse, and it is 50 that thread corresponding to the moment, which starts the upper limit, and under One extracting cycle database does not receive new waiting task, therefore, terminal device can by two task response cycles, , should although terminal device starts the upper limit in peak hours/period thread can reach 100 to perform above-mentioned 100 waiting tasks Period is free time section, i.e., in the period, the mathematical expectation of the task amount of waiting task is less, not during president Between persistently get substantial amounts of waiting task, therefore relatively low thread can be kept to start the upper limit, even if running into what burst increased Waiting task, still can progressively it be responded.

Fig. 3 shows a kind of specific implementation flow chart of the method for adjustment for thread that third embodiment of the invention provides.Ginseng As shown in Figure 3, a kind of method of adjustment of the thread provided relative to embodiment described in Fig. 2, the present embodiment is further comprising the steps of, Details are as follows：

Further, before S101, the method for adjustment of the thread also includes：

In S301, history service response record is obtained；Wherein, the history service response record includes each period Waiting task information and hardware resource operation information.

In the present embodiment, terminal device will generate corresponding pending after the pending task of every secondary response Business response record, wherein, the waiting task response record specifically includes：When responding opening time, response deadline, performing The information such as length, hardware resource occupancy situation, response waiting time.Terminal device obtain corresponding to each waiting task appoint It is engaged in after response record, then can determines the quantity of waiting task included in different time sections, and the end of each period The Expenditure Levels of the overall hardware resource of end equipment, then generate history service response record.

In the present embodiment, hardware resource operation information includes but is not limited to following a kind of or at least two combinations：CPU Running situation, the occupancy situation of internal memory, the running temperature of terminal device, reading and writing data speed etc..Because hardware resource is run Information except internal factors such as the task quantity with currently responding mutually outside the Pass, also with outside such as computer room temperature, voltage, power etc. because Pass is known as, therefore, terminal device not only obtains the waiting task information of each period, also obtains hardware resource operation letter Breath, and history service response record corresponding to generating, during to determine that thread starts the upper limit, it is outer both to consider that internal factor further contemplated Influence factor of portion's environment to terminal device.

In S302, recorded based on the history service response, generate pair that the thread starts the upper limit and temporal information It should be related to.

In the present embodiment, different time sections or task extracting cycle during terminal device records according to history service response Corresponding pending number of tasks, determine pending number of tasks average in each period, so as to obtain pending number of tasks with The variation tendency of time passage.Terminal device is based on the pending number of tasks variation tendency, obtain determine thread start the upper limit with The factor I of the corresponding relation of temporal information.

In the present embodiment, different time sections or task extracting cycle during terminal device records according to history service response Corresponding hardware running information, determine the running status of terminal device in each period, the running status include loading condition, Operational efficiency situation and abnormality incidence, so as to obtain the variation tendency of running status over time.Terminal device is based on The running status variation tendency, obtain determining the factor Ⅱ for the corresponding relation that thread starts the upper limit and temporal information.

In the present embodiment, terminal device starts the upper limit and temporal information according to factor I and factor Ⅱ generation thread Corresponding relation.Alternatively, factor I specially averagely performs number of tasks, and factor Ⅱ is hardware operational efficiency, therefore appoints Thread corresponding to one period starts the upper limit：Averagely perform number of tasks × hardware operational efficiency.Illustrative, 8:00 to 8:10 this In one period, the pending number of tasks that terminal device average received arrives is 50, and the speed of period hardware operation reaches volume Determine operating rate, therefore operational efficiency is 100%, therefore the thread startup upper limit is corresponding to the period：50 × 100%= 50.Certainly, the factor I can be the pending number of tasks of period maximum in historical record or minimum pending The mathematic expectaion for number or the pending number of tasks of being engaged in, is not limited one by one herein.Then, factor Ⅱ can also be according to fortune Proportionality coefficient corresponding to the determination of row state, is not also limited, specifically, the running status of terminal device is better, i.e., one by one herein Load is less, operational efficiency is higher and/or abnormality incidence is lower, and its corresponding proportionality coefficient is bigger, then terminal device is at this Period can respond more pending tasks, therefore the thread startup upper limit is higher；Conversely, the operating state of terminal device is got over Difference, its corresponding proportionality coefficient are smaller.Wherein, the proportionality coefficient is the positive number more than 0.

In embodiments of the present invention, terminal device can also record according to history service response, to thread start the upper limit with The corresponding relation list of temporal information is adjusted, and based on above-mentioned purpose, the history service that terminal device obtains the machine first rings It should record, then be learnt by history service response record, improve the accuracy of corresponding relation list.

Fig. 4 shows a kind of method of adjustment S102 for thread that fourth embodiment of the invention provides specific implementation flow Figure.It is shown in Figure 4, relative to embodiment described in Fig. 1 to Fig. 3, institute in a kind of method of adjustment for thread that the present embodiment provides State and the upper limit is started according to the task number and default thread, it is determined that current thread starts number, also comprising S401~ S405, details are as follows：

In S401, judge whether the task number is more than the thread and starts the upper limit.

In S402, if the task number be more than the thread start the upper limit, judge the task number with it is described Whether the first ratio that thread starts between the upper limit is more than default up-regulation activation threshold value.

In the present embodiment, the thread of terminal device starts the upper limit and can be adjusted according to currently practical task number, So that the task disposal ability of terminal device matches with current task amount.It is according to management because default thread starts the upper limit Member or System History record are prejudged what is obtained, and various emergency cases usually occur in real process, because This, terminal device is provided with the flow that adjustment thread starts the upper limit, starts the upper limit the thread is adjusted flexibly.

In the present embodiment, terminal device detects that the task number included in currently pending task library opens more than thread The dynamic upper limit, that is, represent that terminal device can not be completed to respond in this subtask response cycle to all waiting tasks, it is actual Task amount is more than the task disposal ability of present terminal equipment.Now, terminal device is on then calculating task number and thread start The first ratio between limit, and judge whether first ratio is more than default up-regulation activation threshold value.

In the present embodiment, activation threshold value is raised to be used to define the situation whether current task amount belongs to abnormal increase, And whether current task disposal ability is enough to tackle current task amount, without causing large batch of task to overstock and losing Effect.Therefore, if the first ratio is less than or equal to up-regulation activation threshold value, then it represents that the current task disposal ability of terminal device is with working as Preceding task amount is matching, starts the upper limit without adjusting thread, maintains current thread to start the upper limit constant；If conversely, One ratio is more than up-regulation activation threshold value, then it represents that current task amount burst increase, and the current disposal ability of terminal device without Method ensures waiting task energy normal response, therefore adjustment thread is started into the upper limit, performs S403 associative operation.

Illustratively, in certain time period, it is 100 that the thread of terminal device, which starts the upper limit, and up-regulation activation threshold value is 300%, the quantity of even a certain moment pending task is then needed to thread beyond more than twice of the disposal ability of terminal device Start the upper limit to be adjusted.If the task number included in current time pending task library is 150, start the upper limit more than thread 100, then the first ratio that terminal device calculating task number and thread start the upper limit is：150/100=150%, less than up-regulation Activation threshold value, then current thread is kept to start the upper limit constant.

In S403, if first ratio is more than default up-regulation activation threshold value, based on first ratio, improve The thread starts the upper limit, and chooses the task number with the smaller value in the thread startup upper limit after raising as institute State current thread and start number.

In the present embodiment, after terminal device detects that the first ratio is more than default up-regulation activation threshold value, then to terminal The thread of equipment starts the upper limit and carries out corresponding adjust.Terminal device is preset with the first ratio and arranged with adjusting the corresponding relation of amplitude Table, according to the first ratio being currently calculated, inquire about first ratio corresponding to regulation coefficient, then pass through the regulation coefficient Increase the thread and start the upper limit.

Illustratively, as described in S402 example, it is 100 that the thread of terminal device, which starts the upper limit, and up-regulation activation threshold value is 300%, current task number is 320, i.e. the first ratio is 320% more than up-regulation activation threshold value, it is therefore desirable to which thread is opened The dynamic upper limit is adjusted.Corresponding relation list of the terminal device based on first ratio with adjustment amplitude, is calculated 320% pair The regulation coefficient answered is 200%, i.e., thread is started into upper limit increasing is twice, that is, it is 200 that the thread after improving, which starts the upper limit,.

In the present embodiment, terminal device is after determining that thread starts the upper limit, then after task number and adjustment Thread starts in the upper limit, chooses a less numerical value and starts number as current thread.Because regulation coefficient is likely larger than First ratio, therefore the thread being actually calculated starts the upper limit and is likely larger than task number.

In S404, if the task number is less than the thread and starts the upper limit, judge the thread start the upper limit with Whether the second ratio between the task number is more than default downward activation threshold value.

In the present embodiment, terminal device can be also suitably adjusted according to current task number in current thread startup Limit, may be according in historical record because terminal device is when setting the corresponding relation of temporal information and the thread startup upper limit The foundation for being currently up the upper limit and being used as setting of each period, thus in order that to obtain the corresponding relation more accurate, and close The thread resources of reason ground distribution terminal equipment, therefore terminal device can also reduce thread according to current task reasonable quantity and open The dynamic upper limit, so that reserved thread can perform other operations.Illustratively, in certain time period, the thread of terminal device starts The upper limit is 100, it is 200% to lower activation threshold value, and it is current that the quantity of even a certain moment pending task is less than terminal device More than twice of disposal ability, then need to be adjusted the thread startup upper limit.If included in current time pending task library Task number is 40, starts the upper limit 100 less than thread, then terminal device computational threads start the second ratio of the upper limit and task number It is worth and is：100/40=250%, more than activation threshold value is lowered, then perform S405 associative operation.

In the present embodiment, when it is determined that task number is less than the thread startup upper limit, then computational threads start terminal device The second ratio between the upper limit and task number, and judge whether the second ratio is more than default downward activation threshold value.If second Ratio, which is more than, lowers activation threshold value, then it represents that and the task disposal ability of terminal device is far longer than current desired task amount, because This will reduce thread and start the upper limit, and perform S405 operation；If conversely, the second ratio be less than or equal to lower activation threshold value, Current thread is then kept to start the upper limit.

In S405, if second ratio is more than default downward activation threshold value, based on first ratio, reduce The thread starts the upper limit, and chooses the task number with the smaller value in the thread startup upper limit after reduction as institute State current thread and start number.

Illustratively, as described in S402 example, it is 100 that the thread of terminal device, which starts the upper limit, and lowering activation threshold value is 200%, current task number is 40, i.e. the second ratio is 250% more than downward activation threshold value, it is therefore desirable to which thread is started The upper limit is lowered.Corresponding relation list of the terminal device based on first ratio with adjustment amplitude, is calculated 250% correspondence Regulation coefficient be 200%, i.e., by thread start the upper limit reduce by one times, that is, decline after thread start the upper limit be 50.

In the present embodiment, after terminal device detects that the second ratio is more than default downward activation threshold value, then to terminal The thread of equipment starts the upper limit and carries out corresponding adjust.Terminal device is preset with the second ratio and arranged with adjusting the corresponding relation of amplitude Table, according to the second ratio being currently calculated, inquire about second ratio corresponding to regulation coefficient, then pass through the regulation coefficient Reduce the thread and start the upper limit.

In embodiments of the present invention, by obtaining the ratio between task number and the thread startup upper limit, it is determined whether need To start the upper limit to thread to be adjusted, so as to which the task disposal ability of terminal device be adjusted flexibly, improve in thread startup The accuracy of limit.

Specifically, terminal device obtains current temporal information and the delivery time of the task first, calculate relative to The waiting time at current time, if the waiting time be more than maximum waiting time, then it represents that the task has failed, and is identified as nothing The waiting task of effect；If conversely, the waiting time is less than or equal to maximum waiting time, then it represents that the task is effective, identification For effective waiting task.

In S502, if the waiting task is invalid, by the waiting task from the waiting task storehouse Delete, and service time-out information is returned to client corresponding to the waiting task.

In the present embodiment, if terminal device detects that waiting task is invalid task, by the waiting task Dote on and deleted in waiting task storehouse, so that it is guaranteed that the waiting task included in waiting task storehouse is effectively to wait to locate Reason task.Further, in order to inform its waiting task failure for sending of the user of service request, terminal device is to pending Pushes customer corresponding to task services time-out information, so that the client initiates task requests again.

In S503, if the waiting task is effective, the remaining effective time based on the waiting task, adjustment The priority of the waiting task.

In the present embodiment, terminal device is then extracted and included in the task if it is determined that the waiting task is effective task Remaining effective time, so as to adjust the priority of the waiting task according to the remaining effective time.Terminal device avoids treating Processing task fails, and is responded first for more urgent waiting task, therefore terminal device will be waited to locate according to each The effecting surplus time of reason task, the priority of remaining time shorter waiting task is improved, and for the effecting surplus time Longer waiting task then maintains its priority constant.
