It will make a small (essentially meaningless) performance improvement on a uniprocessor machine, to quote myself "measurable but not meaningful" in magnitude. This was important when we ran on 386-16 CPUs with 8MB RAM, it means essentially nothing now, other than he should be able to do it. Stupid question #1: you did look in grub.conf to see that you are booting the right kernel? That your new kernel is even in grub.conf? -- Bill Davidsen <davidsen@xxxxxxx> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
