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.
