The Uptime command of the Linux performance testing tool displays how long the server has been running, how many login users there are, and the overall load average evaluation of server performance ). The load average value records the number of processes waiting for execution in the queue for the last 1 minute, 5 minutes, and 15 minutes respectively ). The main evaluation indicator of linux system pressure is the load index of the last five minutes.
