Moreover the purpose here is to control the CPU usage? Firstly the reason I would like the program to slow down is because if the CPU is at 100% the CPU is either operating at the very optimum level or else What this means in real terms is that if you want to run a CPU intensive task you can start it using nice and the scheduler will always ensure that other http://itivityglobal.com/cpu-usage/cpu-limit-linux.html Why not limit the process priority instead?

Besides, the standard APIs only allow you to control the isolate, not the threads within the isolate.

posted 2 years ago While both of these sound interesting... posted 2 years ago Hi, I would like to try and limit the usage of both RAM and CPU in Java. This does not limit CPU usage below 100% but gives other threads and processes more timeslices. You can also lower the priority of a process, but unless the CPU(S) are busy, a process will get as much CPU as it can use.

So you need a tool to measure real CPU usage and through experiments, you could increase the number of threads until the real CPU usage goes to 50%.
