It should set your cpu cores at max speed and not lowering it even when 
you're idle, so this is best to do perf comparisons with Hatari.
If your pc is idle and cat /proc/cpuinfo reports max freq on all cores, 
then it means performance mode is really on and real time scaling is 
equivalent to OFF.
