One last thing: I'm very curious about this disparity: could
you please provide more details?  What versions of Mesa
and the X servers have you been using?  Was the depth exactly
the same?  Could you run glxinfo on both systems?  How did
you build the Fedora X server?  What compiler did you use
and what optimization flags?

There should be no particular reason why Ubuntu would have
better *software* GL rendering performance than Fedora,
although hardy ships with gcc 4.2, which could make a big
difference.
