Abstract
The invention discloses a method for improving performance of a communication server by using a memory pool. The method comprises the steps that the number of concurrent processing of the communication server is obtained from a designated configuration file; a memory block for processing interaction messages of the communication server is applied for in a one-off mode according to the number of concurrent processing; memory is applied for and destroyed according to a service request of the communication server through the management method of the memory pool, so that the response time of the communication server is shortened, and the performance of the server is improved. The configuration file is based on the concurrent processing capability of the communication server. According to the method, the number of current processing is obtained according to the configuration file, the management mechanism of the memory pool is achieved, the response speed of the communication server is increased, the stability of the server is improved, and the service experience of a user or the loyalty index of the user for a service product is promoted.
Description
Technical field
The present invention relates to computer communication network technology and server technical field, relate in particular to a kind of method of using memory pool to promote communication server performance.
Background technology
The communication server, refers to that a management resource in computer communication network externally provides the high-performance computer of business service.They intercept in computer communication network the service request from client, and service request is responded and processed, and are different business service, have enriched network application.Under operating system, dynamic memory management is very consuming time, large especially to effectiveness affects, yet in actual application process, but inevitably often will use the internal memory in heap.But there is birth defect in the Memory Allocation of being undertaken by malloc function or new function etc.: (1) utilizes the memory management function of acquiescence to distribute on heap and releasing memory needs the expensive time; (2) As time goes on, on heap, can form many memory fragmentations, in application program, carrying out internal memory application operation will be subject to larger impact, causes the operation of application program more and more slower.
When application program need to be applied for internal memory regularly to the object of fixed size, often can adopt memory pool (Memory Pool) technology to improve memory management efficiency.Classical memory pool way is the identical fritter internal memories of a large amount of sizes of disposable distribution, by this technology, can greatly accelerate Memory Allocation/dispose procedure.Memory pool technique is applied for internal memory by batch, has reduced internal memory request times, thereby makes operation save the time.When having reduced memory fragmentation generation, the lifting of performance is had to significant help.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of method of using memory pool to promote communication server performance, thereby improves communication server performance, promotes user's business experience or the loyalty to business service product.
For achieving the above object, the present invention proposes a kind of method of using memory pool to promote communication server performance, and the communication server is pre-created the idle stand-by memory block of limited quantity; In communication server operational process, by according to the service request receiving, by internal memory pool managing method, and the idle stand-by memory block of distribution gives this service request use configuration state for using; After this service request processing execution completes, configuration state is idle again, follow-up for the communication server; Described internal memory pool managing method comprises the following steps:
A, the communication server obtain concurrent number initialization thread pond from configuration file;
B, judge whether current time has service request; If so, perform step C; If not performing step F;
C, judge in current time memory pool, whether there is the still memory block in idle condition; If so, perform step D; If not performing step E;
D, internal memory pool managing method distribute a free memory block to use to service request thread; After standby service request is finished dealing with; Internal memory pool managing method reclaims the memory block for this service request; Then perform step F;
E, record that internal memory pool managing method distributes less than memory block; And send service request and process mistake;
F, after time delay Δ t, return to step B.
G, the communication server exit, internal memory pool managing method releasing memory.
By internal memory pool managing method, can improve communication server performance, thereby improve client Operational Visit speed.
Described in step D, the distribution of internal memory pool managing method comprises the following steps:
1), traversal memory pool; If there is free memory block, perform step 2); If there is no free memory block, performs step 3);
2), the state of free memory block in traversal memory pool is set to use; Free counter is done and is subtracted an operation; Usage counter is done and is added an operation; And return to the first address of this memory block.
3), return to null pointer;
Described in step D, internal memory pool managing method reclaims and comprises the following steps:
1) will use the state of memory block to put the free time;
2) free counter is done and is added an operation; Usage counter is done and is subtracted an operation.
Further improvement of the present invention is: step D is used internal memory pool managing method to go to distribute and regain memory block, described internal memory pool managing method to distribute and comprises the steps:
1), traversal memory pool; If there is free memory block, perform step
2), if there is no free memory block, perform step 3);
3), the state of free memory block in traversal memory pool is set to use; Free counter is done and is subtracted an operation; Usage counter is done and is added an operation; And return to the first address of this memory block.
The idle stand-by memory headroom that the described communication server is pre-created limited quantity is specially, and when the communication server starts operation, according to configuration file, obtains concurrent number, creates the idle stand-by memory block of concurrent several fixed sizes.
By configuration file, obtain concurrent number, by concurrent number, carry out the size in specified memory pond.
In described step F, the span of time delay Δ t is 10-100ms.
The invention has the beneficial effects as follows: the present invention by obtaining server concurrent number in specified configuration file; According to the mutual message memory headroom of the disposable application server process of concurrent number, by internal memory pool managing method, realize and will apply for and destroy internal memory to communication server service request, thereby shorten communication server response time improving performance of server, aspect following two, embodied, improved communication server response speed, strengthen the stability of server, promoted user's business experience or the loyalty to business service product: 1) shortened the Memory Allocation time.Because memory pool is to use the front disposable memory block of having applied for, when the communication server is processed service request, do not need to apply for internal memory, thereby saved the internal memory application time.2) reduced memory fragmentation.Because memory pool is to use the front disposable memory block of having applied for, when the communication server is processed repeatedly service request, avoided repeating the possibility of application and destruction internal memory, thereby improved the utilization factor of internal memory.
Feature of the present invention and advantage will be elaborated by reference to the accompanying drawings by embodiment.
Accompanying drawing explanation
Fig. 1 represents communication server internal memory pool managing method structural representation of the present invention.
