I can't speak for Berkeley since I've NEVER run on a vanilla BSD machine, but here at Purdue (ECN) the kernal kicks each proc's nice up to 4 after chewing up 10 minutes of CPU time. The idea is to give large crunchers lower priority so that they don't impact interactive users. Because we have lots of users that run large jobs we have taken it even farther and set a "research" bit that gives long running jobs even lower priority. All in the name of keeping the big crunchers from taking over the machine.... Malcolm Slaney (One of the people running large crunchers)
