It may be interesting to be able to limit the CPU usage for a process so that it does not overload your Server (case of a backup for example ).

The package that allows this is CPULimit You can install via the command :

apt-get install cpulimit

To set up the CPU limitation for a process in particular, you will need to use a screen.

The screen creation :

screen -S limitationCPU

In the screen, one sets up the CPU limitation (in the example below, we will restrict the process with the PID 888 à 50%) :

cpulimit -p 8888 -l 50%

Can then detach the screen using Ctrl + A + D.

If you want to reattach the screen created earlier, just run :

screen -r limitationCPU
