Memory processing method and apparatus, computer apparatus and computer readable storage medium

Abstract

Embodiments of the invention disclose a memory processing method and apparatus, a computer apparatus and a computer readable storage medium, which relate to the technical field of computers and are used for solving the problem of difficulty in full utilization of defragmentation for expanding available memory space in the prior art. The method comprises the steps of performing recycling attempt onmultiple physical pages in a memory of a terminal for multiple times; and when the memory capacity released by the recycling attempt exceeds a release threshold, performing defragmentation on the memory, wherein the process of performing the recycling attempt on the physical pages for one time comprises the steps of judging whether the activity degrees of the physical pages are higher than a recycling standard or not, wherein the activity degrees of the physical pages are used for marking the activity levels of the physical pages, and the values of the activity degrees of the physical pages have positive correlation with the activity levels of the physical pages; and if yes, reducing the activity degrees of the physical pages, otherwise, recycling the physical pages.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a memory processing method and device, a computer device and a computer-readable storage medium. Background technique [0002] During system operation, ensuring sufficient available memory space plays an important role in maintaining high performance of the system, and ways to increase available memory space usually include memory recycling and defragmentation. Physical pages can be reclaimed through memory reclamation, resulting in a large amount of free memory. However, in many cases, the total amount of available memory in the memory is less than the total amount of free memory. This is because frequently requesting and releasing a group of contiguous physical pages of different sizes will inevitably cause many small blocks of free physical pages to be scattered in the physical blocks of allocated physical pages. The resulting problem is that even if there are There...
