JdeBPThat says that it moved to https://github.com/opsengine/cpulimit 12 years ago.
That said, if portability is not a concern, adjusting the max bandwidth of the cpu controllers of a dedicated control group for Chrome processes is the better approach.
Steve Castanooooof.... learning the difference between #taskset and #cpulimit to prevent system overheating has been a painful one! Needless to say, #taskset will lock a process to certain CPU cores, but not limit it's max usage. You can STILL overheat pretty badly! Learned THAT the hard way. #cpulimit on the other-hand, will limit the total CPU power by pausing the process periodically when it goes too high... thus keeping temps down exactly like I needed! #themoreyouknow #linux #cli #bashscripting
David Cantrell 🏏You remember how a few days ago I was all "rah rah #cpulimit is teh awesum"? Well, it annoyed me, so I made it even awesomer: https://github.com/opsengine/cpulimit/pull/116. Alas, the author hasn't touched it in years, so I don't expect that to ever get merged 😞
I just found #cpulimit, which nicely (haha) complements #nice. nice makes your process get out of the way if something else has a higher priority. cpulimit makes it just get out of the way, so if I start something like #ffmpeg going just before bed time the machine won't run the noisy fans but will still have the job done by the time I wake up. It works by throttling a process with SIGSTOP/SIGCONT a bit like how #tcpnice sabotages network connections. https://github.com/opsengine/cpulimit

Installing AUR software on the #pinebookpro can make it hot, word of advice: use #cpulimit
#kdenlive is destroying my cpu cores, trying to render a speedpaint video of my #krita painting... had to use the good ol' #cpulimit

Whoever pointed out #cpulimit on here a few days ago is my flippin' hero.
cpulimit -e firefox -l 50
makes a world of difference. Hopefully I won't have to use it once my 16GB of RAM comes in. But for now it's great. Keeps shit from crashing.
