Well, certainly you're rigth. But I have spare cycles and with 4BSD scheduler
they were handled very well.

Yes. The difference is the same. Like I originally mentioned (on one single
cons25) with seti in the background (doesn't matter if nice is 15 or 20) it's
almost impossible to wait until a "make clean" of a port with little
dependencies (like nvidia-driver) finishes.

I can copy that. That's the reason why I started to try ULE. The notes in the
kernel didn't convince me really;) It was a thread in a newsgroup and after
posting my problems Kris told me to post in -current.
