Identify how many cores and threads your CPU has.

To create a 100% CPU load on your Linux PC, do the following. Thanks to the 'everything-is-a-filesystem' concept used when designing Linux, you don't need extra tools to stress out your CPU. One of great options of the Linux operating system is the amount of useful tools available out of the box even in the base system. Here is a trick you can use to overload your CPU in Linux. For example, if you have replaced your CPU fan or changed something in the cooling system, it is a good idea to test it under heavy load. Sometimes it is useful to stress out your CPU. You can add the -background or -b flag with the command to send the command to the background.RECOMMENDED: Click here to fix Windows issues and optimize system performance If you stop the execution of cpulimit, the CPU usage of that specific process will go back to normal.Ī great solution to prevent this issue is to run cpulimit in the background. Here, cpulimit will restrict the CPU usage of the process as long as it's running. To force a process with PID 81550 to use only 50% of the CPU: sudo cpulimit -p 81550 - limit 50 You can use the -limit or -l flag of the cpulimit utility to add a limit to the resources that a process can use. The basic syntax of the command is: cpulimit -p pidĬpulimit -P /path-to-executable Limit the CPU Usage of a Process -P or -path: Absolute path of the executable file.-e or -exe: The name of the executable file.-p or -pid: The process ID of a process.To use cpulimit, you'll have to pass one of the following three arguments with the command: Therefore, to install it on CentOS and RHEL distributions, you'll have to enable the EPEL repository first. On Arch-based distributions like Manjaro Linux: sudo pacman -S cpulimitĬpulimit is available on the EPEL (Extra Packages for Enterprise Linux) repository. You can install the package on Ubuntu and other Debian-based distributions as follows: sudo apt install cpulimit
