This article describes the performance testing of Linux comes with commands, detailing the use of these Linux-brought tools.First, uptimeThe results of the uptime command include how long the server has been running, how many logged-in users, and

Load is an important indicator of the Linux machine, which intuitively reflects the current state of the machine. If the machine load is too high, then the operation of the machine will be difficult. Linux load is high, mainly due to CPU usage,

Load is an important indicator of the Linux machine, which intuitively reflects the current state of the machine. If the machine load is too high, then the operation of the machine will be difficult.Linux has a high load, mainly due to CPU use,

First, uptimeThe results of the uptime command include how long the server has been running, how many logged-in users, and the overall evaluation of server performance (load average). The load average values are recorded for the last 1 minutes, 5

More and more people are beginning to touch the Linux operating system, from VPS to the brushless system (such as OpenWrt, Tomato), but also essential to a variety of probe and system monitoring interface to see "System average Load" or "load

The concept of Load average originates from UNIX systems, and although the formulas vary from one family to the other, they are used to measure the number of processes that are using the CPU and are waiting for the CPU, in a word, the number of

More and more people are getting started with Linux operating systems, from VPs to flash machine systems for wireless routing (such as openwrt and tomato ), at the same time, the words "average system load" or "load average" will also be seen on a

The top command is a common performance analysis tool under Linux that shows the resource usage of individual processes in the system in real time, similar to the Task Manager for Windows. Here is a detailed description of how it is used.

instruction: Top continuous monitoring of the entire system's program working status.top is an excellent interactive tool that can display real-time information about the current system's processes, including PID, memory occupancy, CPU occupancy,
