Some applications consume a lot of CPU and the fans go mad. Temperature increases and a melting alarm is born in the brain. But there is hope in Linuxland! cpulimit we’ll come to the rescue!!

Example limiting cpu usage to use 1 core ('-c 1'), percentage of CPU to 40% ('-l 40'). And, of course, “how nice is nice to be nice!”

By pid with ‘-p’

nice -19 cpulimit -c 1 -l 40 -p 123456

By name with ‘-e’

nice -19 cpulimit -c 1 -l 40 -e hungryapplication
