Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] In the embodiment of the present invention, at least two memory pools are pre-configured according to the size of the memory, and the memory pools include a common memory linked list and a large memory linked list, receive a user's memory application request, and locate the memory pool according to the requested memory size; When there is available memory in the commonly used memory linked list of the located memory pool, the control reads the memory of the commonly used memory linked list of the memory pool and allocates it to the applicant user; The memory of the large memory linked list o...

Abstract

The invention provides a memory management method, a memory management system and a server, belonging to the technical field of the server. The memory management method comprises the following steps: presetting at least two memory pools which comprise frequently-used memory chain tables and big memory chain tables according to the size of the memory; receiving the user's request for applying for the memory and positioning the memory pool according to the size of the memory applied by the user; controlling and allotting the memory of the frequently-used memory chain table reading the memory pool to the user applying for the memory when there is available memory in the frequently-used memory chain table of the positioned memory pool; controlling and allotting the memory of the big memory chain table reading the memory pool to the user applying for the memory when there is no available memory in the frequently-used memory chain table of the positioned memory pool. The invention has high memory allotting efficiency and high memory allotting concurrency and realizes that the plurality of memory pools correspond to a plurality of parallel threads.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a memory management method, system and server. Background technique [0002] The traditional memory allocation is allocated directly through the functions provided by the operating system, and the specific execution process inside the function is as follows: [0003] 1. Lock the thread lock to prevent other threads from entering. [0004] 2. Take out memory blocks in multiples of 4096 bytes (no matter how much memory the user needs, 4096 is used as a page to allocate). [0005] 3. Release the thread lock and allow other threads to enter. [0006] 4. Return the successfully allocated memory to the user layer. [0007] The above process is sufficient to meet the requirements in ordinary programs, but it will greatly reduce program performance for server programs, specifically: [0008] The memory allocation and release frequency of the server is very high. Taking th...
