On Mac, you can use the graphical tool Activity Monitor to view the CPU and memory usage of the system. So how can I use the command line to view it?For CPU usage, use the top command.You can also use top for memory usage, but the

P-process list in the order of CPU usageM-sort the process list in the order of memory usage During system maintenance, you may need to check the CPU usage at any time and analyze the system status based on the relevant information. In centos, you can use the top command to view CPU usage. After running the TOP Com

If the memory occupied by small objects is never released, the memory occupied by the list will increase continuously, and the memory will gradually be occupied by these large numbers of small objects.

A lack of physical memory affects both the performance of Linux desktop systems and server systems. The first thing to do when your computer slows down is to free up memory. In particular, in a multiuser environment and in a mission-critical server environment, memory consumption becomes more critical because multiple users and application threads compete for mor

Use smem to visually display Linux memory usage Insufficient physical memory has a great impact on the performance of Linux desktop and server systems. When your computer slows down, the first thing to do is to release the memory. Especially in a multi-user environment and a server environment that executes key tasks,

see, the top command is a powerful tool for monitoring the system, especially for system administrators. However, it consumes a lot of system resources. The application instance can use the top command to monitor the process of a specified user. by default, the process of all users is monitored. If you want to view the situation of a specified user, press the "U" key in the terminal and enter the user name, the system will switch to the process runni
