"Obviously?" Hardly. Fedora core 2 (or any linux for that matter)
will use the processor cache just as much as Windows. The lack of
the cache will slow both down quite significantly. If your installation
of FC2 ran fast, then the cache was enabled.
It's possible that Windows obeyed the BIOS setting, and linux didn't, but
that's a different issue.
