Question

Is there a simple way to generate a constant CPU load in Java? Like generate CPU load at 60%.

Answer 1

Have not tested this, but it might roughly work, to make your application work and sleep in the correct ratio. Something like (pseudocode):

load = 60;  
do forever
  time = current_system_time_ms() + load
  while (current_system_time_ms() < time)
     // just consume some time for 60 ms 
  end

  SLEEP(100 - load);  // sleep for 40 ms
end 

Ok, you asked for a simple way, but … 🙂
