Article Title: simple adaptive CPU utilization control in linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Recently, we are working on a virtualization-related demo involving

of CPUs x X0.7.Load average refers to the load of the CPU. It contains information about the sum of the number of processes that the CPU is processing and waiting for CPU processing over a period of time, which is the statistic of the length of the CPU usage queue.The value

Classification:Linux (+)In the desktop version of Linux, it is really convenient to look at these things, and there are graphical tools available. However, on the Linux server version, or remote SSH connection, there is no graphical interface can be manipulated. At this point, if we need to understand this information, we can only rely on the Linux command.In thi
