RE: Schedulers, i've also used kernels with both schedulers on this machine and have noticed no difference in desktop performance. I remember an article on ONLAMP from a few years ago that talked about tuning the system for desktop use, i'll check it out and see if the tunables that are discussed there make any difference. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
