Chris,

I think the bottleneck are disk I/O, don't know how fast are the new
disk compared to the old one.

Take a look on performance monitor on both machines and see the CPU
usage, I think both will be low, maybe the old computer showing a
greater percentage, but I don't think any machine will reach 100%.

Copy a big file on the both machine and measure the speed, and if the
diference speed are around the same you noted on your insert, then, you
could be sure the hard disk are your limit.

If you could add a second disk to this computer (preferably on another
controller), make a raid0 with it (I think you could do it on XP Pro via
software), and performe the same test, I think you will get a much
better time.

see you !
