Hi, I have found that if I run Audacity (sound editor ports/audio/audacity) and do a CPU intensive task (eg noise removal, FFT filter, etc) my system becomes almost unusable (takes seconds for the mouse to respond, X shows signs of getting CPU very very rarely etc). I attempted to fudge a fix by reniceing X -20 and Audacity +10 but it didn't seem to make things any better.. I also found that in top the NICE column bears little resemblance to my setting.. I saw values like -100, -140, and 0. I haven't tried the same thing in SCHED_4BSD..
