Not on Fedora's kernel sources, but with 2.6.11ac7. I based my config on /boot/config-2.6.11-1.14_FC3 and dealt with the additional options with "make oldconfig". Then I browsed the configuration with "make menuconfig", just for fun.
I saw kernel preemption was turned off, so I turned on. Afterwards, I notice the system is noticeably faster. Bootup is faster. Shutdown is faster. The Red Hat manu on GNOME pops up WAY faster. OpenOffice.org loading is faster. I suspect other things are faster too, but I'd have to time them.
So my question is: why isn't preemption enabled in the FC3 packaged kernel? Does it conflict with something I haven't encountered yet? maybe some esoteric hardware combination? My hardware data is below.
Another thing: what crucial patch, if any, am I missing by using 2.6.11ac7 instead of the FC3 packaged kernel?
for the record, this has answered by Dave Jones on the fedora users list itself
