Why? o Better interactivity -- No mouse jerkiness, no sluggish screen updates when switching between virtual desktops, etc. o Better scheduling! I'm serious here. Watching top under SCHED_ULE, I'm seeing 10, 15, 20 seconds go by where ALL processes are sleeping. Processes seem to be spending inordinate amounts of time in the "kserel" state. This, of course, doesn't happen with SCHED_4BSD. I do hope there are no immediate plans to deprecate SCHED_4BSD altogether. It just seems to work a whole lot better for me. I'm probably not alone in this. -- Conrad Sabatier - "In Unix veritas"
