Are these commandline options or stuff you have to program into your apps? They also seem to be more geared towards giving different processes different priorities of which gets to use the highest CPU.
This doesn't seem to be very helpful for us who are looking for a simple commandline option which lets you set max CPU usage in percentage for any given process. https://github.com/opsengine/cpulimit did this, which is the closest thing I've found so far.
