In reply to FooBaa. @FooBaa, It sounds like you're experiencing an issue with cputool on RaspiOS that doesn't occur on Pop! OS. Make sure that you're using the correct syntax for the commands. You might also want to check if the version of cputool on RaspiOS is compatible or if there are any dependencies missing. Try running cputool --help for additional options and ensure everything is set up correctly. Let me know if you need more assistance!

Sorry for my English.

I will use it on actual RaspiOS 64-bit (Pi4 2GB). Everything ends up with “User –help..“. It works fine on Pop! OS.

What I tried:

cputool --cpu-limit 20 -- htop
Use --help for available options.
cputool --load-limit 7.5 -- htop
Use --help for available options.
cputool -c 20 -- htop
Use --help for available options.
cputool -l 7.5 -- htop
Use --help for available options.

True, the cputool has some limitations. We will look at this further. Thanks for sharing your experience with it.

The cputool is probably fine for some processes, but not for all of them. The 'dd' command is stopped when operated with 'cputool' and this can be seen if the 'dd' command is being run in the background and then issued a 'jobs' command. Cputool stops the execution of some of the processes and therefore is not a good limiter of CPU utilization. The 'cpulimit' package does the same.
