However, the short- term scheduling effects are not enough to prevent long-running CPU or I/O intensive processes started at nice 0 from seriously impacting interactive performance. Something else is needed. I did a really snazzy scheduler for our V6 systems, and some day if I ever get the time to work on it, I hope to incorporate some of those ideas into our 4.2 kernel as well.
