And my one line fix: renice 10 `pidof firefox-bin` Instantly my system is snappier (and in fact my system got really laggy after applying the preempt sysctl that everyone recommended before)... Performance issue with firefox maybe :P? I don't see the point of adding an additional layer to complicate the system (and essentially slow it down) if all you're trying to do is better describe the nice'ing problem, unless this logic is what you want to do strictly for desktop users in PCBSD, etc who may not have the technical wherewithal to accomplish this task. Besides, the Linux kernel has different compile time profiles for different workloads, so maybe it just works better for them because they already have a means for describing that functionality, whereas FreeBSD is more generic. It would be nice to describe this in a document though so people could also decide how to tune the system for themselves and not deal with a patch like what's noted above by the penguin crowd because it will invariably fail under some workloads or conditions (I have yet to see a one-size-fits-all solution in this area). <handwaving> SCHED_ULE improvements though should be looked into if possible, because there are some potential items that could be done to cluster processes together better, maybe. </handwaving> Thanks, -Garrett _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "freebsd-performance-unsubscr...@freebsd.org"
