How to configure automatic release of Linux cache

In the Linux system, the automatic release of cache is managed automatically by the operating system. Typically, Linux will automatically release cache based on system usage and resource demands to ensure system stability and performance.

If you want to manually configure the cache release strategy of a Linux system, you can achieve this by modifying the system kernel parameters. The specific configuration method depends on the Linux distribution and kernel version you are using.

Generally speaking, the strategy for cache release can be adjusted by modifying the /sys/fs/cgroup/memory/memory.swappiness file. This file controls the extent to which the system swaps out cache when memory is running low. You can set the value in this file to 0 to disable automatic cache release, or to a suitable value to control the extent of cache release.

Additionally, you can use third-party tools such as sysstat and htop to monitor and manage the cache of a Linux system. These tools can help you understand the cache usage of the system and make adjustments as needed.

In general, the automatic release of cache in the Linux system is managed by the operating system, and manual configuration is usually not required. If you have specific requirements, you can try adjusting by modifying kernel parameters or using third-party tools. However, be cautious in making changes to avoid affecting the stability and performance of the system.
