By the way - as far as I have been able to ascertain all other things
are equal. Both boxes are using the same HP Smart Array 6402/128
controller and all other settings are equivalent - such as the
cache/Accelerator Ratio settings.
Also, if it matters - the block buffer cache is disabled in the small
test program (which I didn't write).
