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? Regards, Roderick
