This has been discussed before. The performance loss from running SMP on a UP x86_64 machine is negligable. (In reply to comment #1) > This has been discussed before. The performance loss from running SMP on a UP > x86_64 machine is negligable. Yes, but it's causing havoc with my WiFi driver (RaLink) -- resulting in a system that won't boot. Why enable it if it's not going to be used anyway? I'm sure I'm not the only one who wants to use a Uniprocessor kernel just to get a a piece of hardware going that won't work with SMP enabled kernels.. actually, this was a regression in FC4 that is being reverted in the next update (should be ready next week). Ignacio's comment only applies to rawhide/FC5 onwards. |
