In Linux, you can limit the CPU usage of a process by using the cpulimit<\/code> command. Here’s how to use it:<\/p>\n

    \n
  1. Install cpulimit<\/code> on your Linux system, if it is not already installed. You can do this using your distribution’s package manager. For example, on Ubuntu or Debian, you can run:\n
    \n
    <\/div>\n
    sudo apt-get<\/span> install cpulimit
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  2. Identify the process ID (PID) of the process you want to limit. You can use the pidof<\/code> command to get the PID of a running process. For example, to get the PID of the firefox<\/code> process, you can run:\n
    \n
    <\/div>\n
    pidof firefox
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  3. Use the cpulimit<\/code> command to limit the CPU usage of the process. The basic syntax of the command is as follows:\n
    \n
    <\/div>\n
    cpulimit -l LIMIT -p<\/span> PID
    \n<\/code><\/div>\n<\/div>\n

    Replace LIMIT<\/code> with the maximum percentage of CPU usage you want to allow for the process, and PID<\/code> with the PID of the process you want to limit.<\/p>\n

    For example, to limit the firefox<\/code> process to 50% CPU usage, you can run:<\/p>\n

    \n
    <\/div>\n
    cpulimit -l 50<\/span> -p $(pidof firefox)
    \n<\/code><\/div>\n<\/div>\n

    This will limit the firefox<\/code> process to using a maximum of 50% of the CPU.<\/p>\n

    Note that cpulimit<\/code> works by pausing and resuming the process at a given frequency, so the actual CPU usage may fluctuate around the limit you set.<\/li>\n

  4. If you want to remove the CPU usage limit, you can kill the cpulimit<\/code> process or use the killall cpulimit<\/code> command to kill all cpulimit<\/code> processes.<\/li>\n<\/ol>\n

    That’s it! You have successfully limited the CPU usage of a process in Linux using cpulimit<\/code>.<\/p>\n","protected":false},"excerpt":{"rendered":"
