There's this Linux kernel patch that allows for timeslice tuning. It's
got the following rules of the thumb:
* The optimal setting is your CPU's speed in MHz's / 2
* ...but there is no point in going above 1000 Hz
* ...and be sure to use multiples of 100 Hz
I am everything but an expert at scheduling, but somehow this makes
sense: i.e. one jiffy for the scheduler and one jiffy for the process.
Does all of this make any sense or is it just a load of hooey?
