You have to be root to use idprio, requiring a suid wrapper, which strikes me as kludgy. The worst part is that idprio and rtprio don't entirely work. An idprio process can still interfere with a rtprio process. :-( Rtprio is false advertising, it is *not* real time. Rtprio is really just pigprio.

Nice (and rtprio/idprio) only care about CPU usage, not I/O usage. Nice and friends do very little to throttle a process that is hogging I/O resources. Also: Some device drivers (SATA drivers, firewire, perhaps others) hog the CPU for obscene lengths of time, locking out even other device drivers. This causes DATA TO BE LOST. :-( :-( :-( Some SATA drivers still don't support NCQ, causing *horrible* logjams. NCQ also gives 10-13x the speed. ---switch to metadiscussion--- > Also, does this really need to be cross-posted to -current, -hackers, > and -performance? The question is why does cross posting result in receiving duplicates? (Usenet was much better for this type of discussion.)

Lately I've been skimming most sites (including phoronix) with images turned off and they load *SO* much faster. _______________________________________________ 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"
