Why should there be anything surprising?

Your two platforms were:

> Time on Windows XP Desktop System with P3 Processor and 512 RAM

and

> Time on Windows 2000 Server System with P3 Processor and 1.5 GB RAM

But you missed to provide very important data -- the CPU speed of the two
P3-s -- it can be quite different.

Also, the second platform has thrice the memory of platform 1.

Most probably on platform one the RAM was insufficient, therefore swapping
and thrashing occured.

On platform 2 the memory was three times more, there was no swapping, (the
CPU speed was probably faster) so it took dramatically less time to
complete.

As explained above, this is not discrepancy, but a logical fact.
