How does Kirin operating system monitor and optimize system performance?

Introduction:
With the rapid development of computer technology, operating systems play a vital role in modern computers. Optimizing the performance of your operating system is crucial to improving overall computer performance and operating efficiency. Kirin operating system, as an open source operating system based on Linux, provides a wealth of performance monitoring and optimization tools. This article will introduce the commonly used performance monitoring and optimization methods and code examples in Kirin operating system.

1. System performance monitoring tools
Kirin operating system provides some commonly used performance monitoring tools, such as top, htop and sar. The following describes how to use two of the commonly used tools and examples.

1. top
   top is a very commonly used performance monitoring tool in Linux systems. It can be used to view the running status of the system in real time, including CPU usage, memory usage, process information, etc. Through the top command, we can easily find out the processes that occupy higher system resources and system bottlenecks.

Sample code:

$ top

2. htop
   htop is a more powerful performance monitoring tool on Linux. Compared with top, it provides more functionality and interactive interface. htop can display more process information, such as process tree, process status, etc., and supports interactive operations through the mouse.

Sample code:

$ htop

2. System performance optimization method
After understanding the performance status of the system, we can adopt different optimization methods according to the specific situation. The following introduces several commonly used system performance optimization methods and sample codes.

1. Process Management
   Processes are the most basic resources in the operating system. Proper management of processes can effectively improve the overall performance of the system. Through the process management commands provided by Kirin Operating System, we can view running processes, end unnecessary processes, etc.

Sample code:

查看正在运行的进程：$ ps -ef
结束指定进程：$ kill 1234

2. Disk management
   Disks are important storage media in computers. Proper management of disks can improve the read and write performance of the system. For disk management in Kirin operating system, we can improve performance by optimizing the file system and allocating disk space.

Sample code:

优化文件系统：$ tune2fs -o journal_data_writeback /dev/sda1
分配磁盘空间：$ fdisk /dev/sdb

3. Memory management
   Memory is an important resource in the computer. Optimizing memory management can improve the efficiency of system operation. Kirin operating system provides some commands to optimize memory management, such as checking memory usage, cleaning up memory, etc.

Sample code:

查看内存使用情况：$ free -m
清理内存缓存：$ sync && echo 3 > /proc/sys/vm/drop_caches

4. Network management
   The network is an important communication method in computers. Optimizing network management can improve the network transmission efficiency of the system. Kirin operating system provides some commands to optimize network management, such as viewing network connections, adjusting network parameters, etc.

Sample code:

查看网络连接：$ netstat -an
调整网络参数：$ sysctl -w net.core.rmem_default=26214400

Summary:
As an open source operating system based on Linux, Kirin operating system provides a wealth of performance monitoring and optimization tools. By using system performance monitoring tools, we can view the running status of the system in real time. At the same time, we can use optimization methods such as process management, disk management, memory management, and network management to improve system performance according to specific circumstances. The above are only some commonly used performance monitoring and optimization methods. In actual applications, more optimization measures can be taken according to needs to improve the performance of the operating system.
