Server tuning Linux server and achieving best performance

With the development of the Internet era, Linux servers have been widely adopted and applied to various I/O tasks such as websites, databases, applications and so on. In order to ensure normal operation and stable service of these tasks, it is necessary to optimize the popular Linux server performance.

The adjustment of Linux server performance mainly includes two aspects. One is external adjustment and the other is internal adjustment. External adjustment mainly includes procuring hardware components and system environment, setting users and passwords, setting up the network, configuring user rights and so on. Internal adjustment is mainly the adjustment of the operating system and software. Most of the Linux operating system parameters are determined by the environment, but for better performance, it is necessary to make certain proper adjustments to some of its systems.

First of all, adjust the number of IP connections, for example, use

a command such as sysctl -w net.ipv4.tpc_tw_recycle=1 to set ip connections

so that it can better use the available resources and give users better performance. Secondly, modify memory parameters such as setting vm.swappiness to 0 so that the system can better allocate resources among processes to minimize latency.

In addition to the adjustment of parameters, the update of software is also very important. Software can often contain bug fixes and performance enhancements. Therefore, it is necessary to make regular software updates so that the system can achieve better performance.

In summary, if you want to optimize the performance of Linux servers, it is necessary to make adjustments to the external environment, adjust operating system parameters and make updates to software. It will make your Linux servers run better and give users better performance.
