Have you used the GUB-compiled binary package, or Fedora's built-in or a
self-compiled package?  I think that you probably can only make
platform-specific comparisons if you use GUB for all.

Of course, when the speed of our GUB-provided binary for Linux differs
vastly from that of self-compiled binaries, that's also reason for
worrying.
