    Without using cpulimit the process uses 95-100% of the cpu (4 cores / 8 threads).

    Using this code: cpulimit --pid 17918 --limit 75
    Makes my cpu use only 8-12%…..

    Also tried: cpulimit --pid 17918 --limit 75 -cpu 4 and --cpu 8
    Same result… the cpulimit module seems glitched.

    Sad that Linux is so shit in 2019 since Windows could have controlled the CPU usage 100% precise since like 2004 and that from the task manager without installing additional shit and waste more time.

    --background or -b is no longer a valid option.

    such tool is a bit outdated for these times, since long time ago, Linux allows controlling these kind of resources via cgroups, in a much more way than using SIGSTOP/SIGCONT. Indeed in current times, you have systemd-run to do these kinds of things and much more.

      Yap, that’s true. Thanks for pointing this out, we’ll soon organize an article about cgroups and resource control especially under systemd. However, these tools are still useful even in current Linux systems.
