Have you tried some other benchmarks on those two machines?
I don't actually think the results are as crazy as they look.
"Celeron", like "Pentium", is the name of several very different CPUs.
Presumably the 1GHz one is a cut-down Pentium III and the 2.6GHz one
is a cut-down Pentium 4. Now ...
- Clock for clock, the P3 is much faster than the P4.
(The P4's design scales better to high clock speeds.)
- The P4 is, IIRC, really quite bad for chess programs.
So if it's also true that
- The Celeronification process (mostly a matter of removing
cache) hurts the P4 worse than it hurts the P3
(which I think is true, but I'm not sure) then the 2.6GHz Celeron
might really, truly, be slower at running Crafty than the 1GHz
Celeron. Just one more lesson in the dangers of believing clock
speeds.
Then again, something might be wrong :-).
