Fedora core (be that FC3 and/or FC4) are optimized for i686 and compatible with i386. They are not optimized for Xeon. According to Fedora devs, such optimization will yield limited improvement. (Which to my own experience, in most part, this is true; using -march instead of -mtune does really increase the code's performance.)
