Abstract

The invention relates to a method and a device for optimizing an internal memory and belongs to the technical field of computers. The method comprises the following steps of when a newly-built process needs to be added into a control group, detecting whether a total value of resources occupied by all processes in the control group at current moment reaches a resource critical value; if the total value of the resources occupied by all the processes in the control group at the current moment reaches the resource critical value, adding the newly-built process into the control group which is not limited by a resource threshold value; swapping out the resources occupied by idle processes in the control group, so that the total value of the resources occupied by all the processes in the control group is smaller than the resource threshold value. According to the method and the device, the problem of influence on the running speed of a terminal caused by longer delay of the executed swapping-out operation when the terminal adds the newly-built process to the control group while executing the swapping-out operation is solved, and the effect of reducing the operation delay during the compression of the internal memory is achieved.

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 (Control Group, Cgroup), and limit the total resource value that the processes in the control group can occupy by setting the resource threshold; when the terminal When it is necessary to add a newly created process 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 that has not been ...
