Two CPUs both cranking a lot of data to disk will certainly be limited by
that disc and it's interface speed. Put a 2.4 with a fast disk against a
3.2 with a slow disk (or bottlenecks in I/O) and it would come as no
surprise to see them coming up nearly equal. It's only as fast as the
slowest part of the process. Want better performance, then get a 10k RPM
drive and a faster I/O card for it.
