Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall in the protection scope of this application.

Applicant has found in the course of the research: pay close attention to mobile terminal disk read-write speed be a realization it is more complicated, The scheme that influence factor is more and practical significance is not high.The application no longer goes the disk read-write speed of concern mobile terminal, and It is to pay close attention to the IO outstanding message of the operating system of mobile terminal, and reflect IO performance based on IO outstanding message.

IO method for testing performance provided by the present application can integrate in the operating system of mobile terminal, can also be used as one A application integration is not limited this in mobile terminal.Since the application can detect IO in mobile terminal use process Performance, it is possible to obtain the real-time IO performance of mobile terminal and application, real-time is higher.

It is understood that using IO method for testing performance as an application integration in the case where mobile terminal, can It is modified to avoid to operating system.Therefore, using IO method for testing performance as an application integration in mobile terminal scheme, Applicability is higher.

The application both can detecte the IO performance of mobile terminal, can also detect the IO performance of application.Separately below to shifting The detection process of the IO performance of the IO performance and application of dynamic terminal is illustrated.

First part: the IO performance of mobile terminal is detected.

According to one embodiment provided by the present application, a kind of embodiment one of IO method for testing performance is provided.

Step S101: from the state operating file of operating system, I/O latency and CPU runing time are obtained.

State operating file/the proc/stat for obtaining operating system, has recorded in the state operating file of operating system Many system operational parameters, for example, IOWait time and CPU runing time.

The IOWait time refers to after mobile terminal-opening operation, since I O scheduling leads to the waiting time of mobile terminal；? In the IO waiting process of mobile terminal, mobile terminal does not have process that can run, and the CPU of mobile terminal is in idle condition (idle state).

It is understood that the IOWait time the long, indicate time that mobile terminal is in idle condition by I O scheduling more It is long.CPU runing time is the time value of lasting timing after mobile terminal-opening operation.

Step S102: the ratio of the I/O latency Yu the CPU runing time is calculated.

Step S103: in the case where the ratio is greater than the first ratio, it is abnormal to determine that the IO performance of mobile terminal occurs.

It is understood that indicating that the degree of IO abnormal performance is bigger in the case where ratio is bigger.

When the ratio is not more than the first ratio, it can reflect that mobile terminal does not have from side and fall into a long wait, but Mobile terminal does not occur IO abnormal performance not necessarily.

Wherein, the first ratio is a threshold limit value, and the specific value of the first ratio can be set by technical staff, again Without limitation.

State operating file/proc/stat of operating system further includes running state of a process；Running state of a process can To include:

R state: Running or runnable (on run queue), task is currently running state.

S state: Interruptible sleep (waiting for an event to complete) task is etc. The suspend mode to some event.

D-state: Uninterruptible sleep (usually IO).

Certainly, running state of a process can also include other states, and this is no longer going to repeat them.

Wherein, D-state is not interruptable sleep state, and the process in the state is usually waiting free time IO.Such as Free disk IO is waited, dormant network IO is waited, alternatively, waiting other idle peripheral hardware IO.

Therefore, the application can be in state operating file/proc/stat of operating system, and acquisition is in can not terminal Dormant number of processes (namely number of processes in D-state), be used to assist determine mobile terminal IO performance.

Can count in the dormant number of processes that can not interrupt, if in it is not interruptable it is dormant into The ratio of number of passes amount and all number of processes is greater than the second ratio, then it is abnormal can to determine that the IO performance of mobile terminal occurs.

That is, occupying most of number of processes in not interruptable dormant number of processes in all number of processes When, then it is abnormal can to determine that the IO performance of mobile terminal occurs.

Or, it can be determined that whether it is greater than the second quantity in not interruptable dormant number of processes, is being in In the case that not interruptable dormant number of processes is greater than the second quantity, illustrate in not interruptable dormant Number of processes is more, can determine the IO abnormal performance of mobile terminal.

It is understood that indicating IO in the case where more in not interruptable dormant number of processes Degree that can be abnormal is bigger.

According to one embodiment provided by the present application, a kind of embodiment two of IO method for testing performance is provided.Referring to figure 2, comprising the following steps:

Step S201: the scheduling information file of operating system is determined.

In the scheduling information file (Sched file) of operating system, it will usually in the scheduling of middle record the process and thread Information and IO outstanding message.

Step S202: the outstanding message of process is obtained from the scheduling information file of operating system.

Outstanding message may include that the I/O latency of process and IO wait number.

Step S203: the IO performance of mobile terminal is determined by the outstanding message of process.

There are three types of implementation, three kinds of implementations can be used alone and can also be used with random incorporation this step tool, then It is secondary without limitation.

The first implementation: the IO performance of terminal is determined by the waiting number of process.

When process temporarily can be used without IO, process is just in waiting I/O state, waits number that can add 1.Usually In the case of each process have the case where waiting IO, so the waiting number non-zero of most of process.Therefore one is set in advance If number, for indicating the more threshold value of process waiting number.

It determines the size relation of each process waited between number and preset times, and counts and wait number greater than default The process of number.

It is greater than the second quantity in the number of processes for waiting number to be greater than preset times, then illustrates that mobile terminal has more be in The process of IO can not be obtained, that is, determines the IO abnormal performance of mobile terminal.

If the ratio for the number of processes and all number of processes for waiting number to be greater than preset times is greater than the second ratio, really Determine the IO abnormal performance of mobile terminal.

It is understood that indicating IO performance in the case where waiting number greater than the number of processes of preset times more Abnormal degree is bigger.

Second of implementation: the IO performance of terminal is determined by the waiting time of process.

In the case where process is in and waits IO, the waiting time of process can be gradually increased.Each process under normal conditions The case where waiting IO is had, so the waiting time non-zero of most of process.Therefore a preset time is set, for indicating Process waiting time more threshold value.

It determines the size relation between the waiting time and preset time of each process, and counts the waiting time greater than default The process of time quantity.

It is greater than preset quantity in the number of processes that the waiting time is greater than preset time, then illustrates that mobile terminal has more be in The process of IO can not be obtained, that is, determines the IO abnormal performance of mobile terminal.

Alternatively, being greater than the number of processes of preset time and the ratio of all number of processes greater than the second ratio in the waiting time Value, it is determined that the IO abnormal performance of mobile terminal.

It is understood that indicating IO performance in the case that the number of processes for being greater than preset time in the waiting time is more Abnormal degree is bigger.

The third implementation: IO performance is determined by the difference of the waiting time of process.

The schedule file of operating system can be periodically acquired, for example, obtaining in multiple scheduling information files.In multiple tune It spends in file and determines the difference of the waiting time of same process, if the increasing degree of waiting time is greater than predetermined amplitude, it is determined that The IO abnormal performance of mobile terminal.

Referring to table 1, for the citing for calculating waiting time difference by multiple scheduling information files.

Table 1

Under normal circumstances, the difference of the waiting time of the same process in adjacent scheduling information file should be similar consistent 's.Increasing degree if the waiting time indicates that the difference of waiting time increases suddenly if being greater than predetermined amplitude, can determine shifting The IO performance of dynamic terminal occurs abnormal.

For example, the difference of the waiting time of process 1 suddenly increases to 500ms (above-mentioned table 1 from 50ms in the above-mentioned citing of table 1 This implementation process by way of example only does not represent truth), then it can determine the growth width of the difference of waiting time Degree is greater than predetermined amplitude, so that it is determined that exception occurs in the IO performance of mobile terminal.

It is understood that indicating that the degree of IO abnormal performance is got in the case where the increasing degree of waiting time is bigger Greatly.

According to one embodiment provided by the present application, a kind of embodiment three of IO method for testing performance is provided.Referring to figure 3, comprising the following steps:

Step S301: the state operating file and scheduling information file of operating system are determined.

Determine the state operating file/proc/stat and scheduling information file Sched of operating system.

Step S302: it obtains from the waiting time for obtaining process in scheduling information file and from the state operating file The runing time of process.

The waiting time of each process is obtained from scheduling information file Sched, is then obtained from state operating file The runing time of each process.

Step S303: the ratio of the runing time of the waiting time and process of calculation procedure.

Step S304: it is greater than the first quantity in the number of processes that ratio is greater than the first ratio, or, ratio is greater than the first ratio Number of processes and all number of processes ratio be greater than the second ratio, it is determined that the IO abnormal performance of mobile terminal.

In the case where the ratio of the waiting time of process and the runing time of process is greater than the first ratio, then illustrate process In falling into a long wait state.

The number of processes that ratio is greater than the first ratio is counted, if the number of processes that ratio is greater than the first ratio is more, table Show more in the process for falling into a long wait state.

It is greater than the first quantity in the number of processes that ratio is greater than the first ratio, it is determined that the IO abnormal performance of mobile terminal. Alternatively, being greater than the number of processes of the first ratio and the ratio of all number of processes greater than the second ratio in ratio, it is determined that mobile The IO abnormal performance of terminal.

It is understood that indicating IO performance in the case where the number of processes that statistics ratio is greater than the first ratio Abnormal degree is bigger.

According to one embodiment provided by the present application, a kind of example IV of IO method for testing performance is provided.Referring to figure 4, comprising the following steps:

Step S401: the state operating file and scheduling information file of operating system are determined.

Step S402: I/O latency and CPU runing time are obtained from the state operating file of operating system, from operation The outstanding message of process is obtained in the scheduling information file of system.

Step S403: the ratio of the I/O latency Yu the CPU runing time is calculated.

Step S404: by the ratio and the outstanding message of process, the IO performance of mobile terminal is determined.

Determine whether mobile terminal IO abnormal performance occurs by two dimensions in the present embodiment, one of dimension be by Determine whether mobile terminal IO abnormal performance occurs based on ratio according to the mode of embodiment one；Another dimension is according to implementation The mode of example two or embodiment three determines whether mobile terminal IO abnormal performance occurs based on the outstanding message of process.

In the case where two dimensions determine that IO abnormal performance occurs in mobile terminal, determine that IO performance occurs in mobile terminal It is abnormal.

Through the foregoing embodiment the application may be implemented it is following the utility model has the advantages that

The application no longer pays close attention to disk read-write speed, but determines the state operating file and scheduling information file of operation, Including the IO outstanding message of mobile terminal.I.e. by the IO outstanding message in state operating file and scheduling information file come The IO performance of side reflection mobile terminal.

Second part: IO performance is carried out to the application of mobile terminal and is detected.

According to one embodiment provided by the present application, a kind of embodiment five of IO method for testing performance is provided.Due to right The implementation procedure of each application is consistent, therefore is illustrated by taking an application to be detected as an example.

Referring to Fig. 5, comprising the following steps:

Step S501: the scheduling information file of operating system is determined.

Step S502: the outstanding message and line to be detected using occupied process is determined in the scheduling information file The outstanding message of journey.

In the scheduling information file of operating system, it will usually the IO etc. in Sched file including record the process, thread To information, outstanding message may include I/O latency, and IO waits number etc..

In scheduling information file, process corresponding with the mark of application to be detected and thread can be searched, to obtain Process outstanding message and thread outstanding message to be detected using occupied process and thread.

Step S503: by described to be detected using the outstanding message of occupied process and the outstanding message of thread, really The IO performance of the fixed application to be detected.

Present embodiments provide two kinds of implementations of this step.

The first implementation:

It is greater than preset times in the waiting number to be detected using occupied process, or, shared by application to be detected It is greater than preset times with the waiting number of thread, it is determined that the IO abnormal performance of the application to be detected.

In the case where the waiting number to be detected using occupied process is greater than preset times, can determine to be detected The IO abnormal performance of application.It is understood that the IO of application to be detected can be determined only by the process of application to be detected Performance.

In the case where the waiting number to be detected using occupied thread is greater than preset times, can determine to be detected The IO abnormal performance of application.

Since the corresponding process of application to be detected may include multiple threads, some IO wait situation that may not be reflected in Where application to be detected in process, but it is reflected on one or more threads in process.Therefore, the present embodiment can also obtain The waiting number for obtaining thread can determine the IO of application to be detected in the case where the waiting number of thread is greater than preset times Abnormal performance.

Conversely, the waiting time to be detected using occupied process be not more than preset time, and, it is described to The waiting time of the occupied thread of detection application is not more than preset time, it is determined that the IO performance of the application to be detected is just Often.

Second of implementation:

It is greater than preset time in the waiting time to be detected using occupied process, or, shared by application to be detected It is greater than preset time with the waiting time of thread, it is determined that the IO abnormal performance of the application to be detected.

That is, being greater than preset time in the waiting time to be detected using occupied process, it is determined that described to be checked Survey the IO abnormal performance of application.It is understood that application to be detected can be determined only by the process of application to be detected IO performance.

It is greater than preset time in the waiting time to be detected using occupied thread, it is determined that described to be detected to answer IO abnormal performance.

The first implementation uses the waiting time in second of implementation using number is waited, and in addition to this second Kind implementation is that implementation is similar with the first, and details are not described herein.

Conversely, if the waiting number to be detected using occupied process be not more than preset times, and, if it is described to The waiting number of the occupied thread of detection application is not more than preset times, it is determined that the IO performance of the application to be detected is normal.

Step S504: the IO of the adjustment application to be detected uses operation.

In the case where the IO abnormal performance of application to be detected, it is possible to reduce the IO usage amount of the application to be detected.

For example, reducing the IO read-write amount or access time of application to be detected；The parallel of the application to be detected is reduced to appoint Business quantity；It is used or, adjusting the modes such as the priority of process or thread with outstanding message to reduce the IO of application to be detected Operation, to alleviate the IO performance of application to be detected.

After the IO performance recovery of application to be detected is normal, when can increase the IO read-write amount or read-write of application to be detected Between, increase the modes such as the parallel task quantity of application to be detected, to increase the IO of application to be detected using operation, thus adapt to Detect the IO performance of application.

After through multiple reversed adjusting, application to be detected can be made preferably to adapt to the performance of mobile terminal.It adjusts The IO performance of whole application to be detected, to reach IO performance balance point, to be conducive to be promoted the IO performance of application to be detected.

Present invention also provides a kind of IO performance detecting systems, including multiple mobile terminals and server.
