proc stat cpu usage

Generally, for processes that require a large amount of CPU computing, the higher the front-end pressure, the higher the CPU utilization. However, for I/O network-intensive processes, even if there are many requests, the CPU of the server may not be

Reprinted from: http://blog.csdn.net/pppjob/article/details/4060336Under Linux, CPU utilization is divided into user state, System State and idle state, respectively, the CPU is in user state execution time, system kernel execution time, and idle
