A tool to throttle the CPU usage of other processes. More information: <http://cpulimit.sourceforge.net/>.

  • Limit an existing process with PID 1234 to only use 25% of the CPU:
    cpulimit --pid 1234 --limit 25%
  • Limit an existing program by its executable name:
    cpulimit --exe program --limit 25
  • Launch a given program and limit it to only use 50% of the CPU:
    cpulimit --limit 50 -- program argument1 argument2 ...
  • Launch a program, limit its CPU usage to 50% and run cpulimit in the background:
    cpulimit --limit 50 --background -- program
  • Kill its process if the program's CPU usage goes over 50%:
    cpulimit --limit 50 --kill -- program
  • Throttle both it and its child processes so that none go about 25% CPU:
    cpulimit --limit 25 --monitor-forks -- program
