Abstract

The present invention relates to a method and a device for optimizing memory. The method includes: when a newly created process needs to be added into a control group, detecting whether a total resource value occupied by all processes in the control group at the current moment reaches a resource critical value (101); if detecting that the total resource value occupied by all processes in the control group at the current moment reaches the resource critical value, adding the newly created process into a control group that is not restricted by a resource threshold (102); and performing a swap-out operation on resources occupied by an idle process in the control group, so that the total resource value occupied by all processes in the control group is less than the resource threshold (103). The present invention reduces the time delay of the operation while compressing the memory.

Description

technical field [0001] The present disclosure relates to the technical field of computers, in particular to a memory optimization method and device. Background technique [0002] As the number of applications running on the terminal increases, the available memory of the terminal decreases, which affects the smoothness of the running applications. Therefore, it is necessary to optimize the memory of the terminal. [0003] When performing memory optimization, the terminal can divide the created multiple processes into a control group (ControlGroup, Cgroup), and limit the total resource value that the processes in the control group can occupy by setting the resource threshold; when the terminal needs When a newly created process is added to the control group and it is detected that the total resource value of the control group exceeds the resource threshold after joining, a swap operation is performed, that is, the terminal replaces the idle process corresponding to the idle p...
