I even tried using Cpulimit to try limiting it to 90%. Idk, the program tells to set a number from 0 to 400 which would be the percentage of the cpu and since mine has 4c/4t i´ve ran with 360, which managed to limit around 90%. Also, i´ve tried using 90 as argument and CPU was limited aroud 20% to 25% of usage, so I think I use it right. Source: 9 months ago

A few days ago I discovered cpulimit. It's a great tool that nicely (haha) complements nice. Where nice is normally used to reduce the amount of CPU a process uses by changing it priority, a niced process can still end up using more CPU than you want, and will of course use all that it wants if nothing with a higher priority comes along. - Source: dev.to / about 1 year ago

Thanks for your elaborate notes! This is helpful information. When I tried your commands, on Arch via libcgroup-git, `cgcreate -g cpu:cpulimit` only results in `cgcreate: can't create cgroup cpulimit: Cgroup, requested group parameter does not exist`, for some reason. But this is not a support ticket, I have not researched this at all yet. But cgroups only limit some processes anyway, never the entire... - Source: Hacker News / over 2 years ago

A bit different from what you're asking but for this kind of use, I generally use cpulimit (link). It allows you to artificially limit the amount of CPU consumed by a process. Source: almost 3 years ago
