(or timeslice if you will) Why not use small quantum values for high pri processes and long for low pri since the high pri processes will preempt the low pri processes anyways. And for a server working under load with only a few processes (assuming they are all low pri) would lessen the context switches. And a system with "interactive load" as well would, as i said, preempt the lower pris. But this could also cause a problem... Imho there should be a "min quantum value" so that processes can't preempt a process that was just scheduled (i dunno if this is implemented already though).=20 Imho this would also make it easy to get the right pri for highpri processes since the quantum value is smaller and if you use it all up you get demoted. Anyways, I've been wondering about the inverted values in the scheduler and for a mixed load/server load i don't see the benefit... =3DP PS. Do not forget to CC me since i'm not on this list...
