Windows has (offhand) ~ 30 scheduling levels. It has priority classes,
which 'group' processes, and then relative priorities within each
class.IIRC you can check sched,cc via CVS to see the actual mapping I
used, it's not linear as such, but nearly so.
Thomas,
those tests show nothing other than the time it takes to push the iso
through to a bitbucket. Unless there is serious other load on the CPU,
the time *should* be constant.
