I have got a linux system, which runs an application. Which meant to utilize all the CPU it can. However, there use to be 0.2% CPU idle. But recently its always 0.0% idle. I noticed on top that SYSTEM% is going high. I think that's what taking 0.2% CPU. This CPU eating application runs as a user.
Now, my question is, is there anyway I can limit a particular user to 80% of CPU. So, that user can never go more than 80% and I will always have some CPU free for SYSTEM.
As for cpu usage you cannot specifically say that a process should use 0% of CPu,etc
You can reduce the priority of process and allow other system processes to use CPU
