Problems solved by technology

[0004] Although the use of off-heap memory of the virtual machine (jvm) can effectively avoid the performance loss caused by garbage collection, it lacks a convenient and effective memory management unit to manage and track the use of memory, which can easily lead to low allocation and usage efficiency, memory fragmentation, etc. question

Abstract

The invention discloses a method and device for managing an out-of-heap memory, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: acquiring a memory size requested to be allocated from a memory allocation request; judging whether available memory pages exist in the allocated memory pages or not according to the size of the memory; if yes, obtaining an available memory page; otherwise, obtaining an available memory block, and obtaining an available memory page from the memory block; and allocating a memory segment for the memory allocation request from the memory page. According to the embodiment, a memory management structure is used for managing and controlling a memory segment which is applied by a user and is not managed by a virtual machine (jvm), the memory is managed in a pooling mode, memory fragmentation is effectively avoided, meanwhile, application and release operations of the memory are reduced, the allocation and recovery efficiency of the memory is greatly improved, the use efficiency of the memory is greatly optimized in a network transmission scene, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for managing out-of-heap memory. Background technique [0002] When creating objects or allocating memory on the virtual machine (jvm) platform, by default, operations are performed on the memory segment managed by the virtual machine (jvm). The reference situation automatically determines when it should be recycled. When the virtual machine platform performs garbage collection, it will copy the memory that is still in use to the new memory space managed by the virtual machine (jvm). Since garbage collection is a very frequent operation , Active memory will be continuously copied back and forth during the garbage collection (GC) process, resulting in performance loss. At the same time, the performance loss caused by continuous memory application and recovery cannot be ignored. Therefore, the virtual machine (jvm) platform It also provides an interface to al...
