I don't recall the details, but while I was playing with
the scheduler last fall Russ and I found that there was a
bug with assigning priorities. Under load the scheduler
was a real dog; I think Russ subsequently fixed it. Doing
so made the system noticeably snappier. I also ran into
some problems with what appeared to be lost clock
interrupts, but never had the time to track things down
completely. As rob pointed out, the new 9p makes a
difference, too.
