Now, i don't wanna start a war or anything...
But it may be interesting to run one of these tests on a Mac to see how 
long it takes.
If you could send me the .sco and .orc files I'll do it while I 
peacefully slumber.
For such large amounts of data, I would expect disk speed to be a factor, 
not just raw cpu speed.
