I got a 57.3 with the same machine running 10.4.8 also, but mine has half a gig less ram. Why the huge disparity? This xbench thing seems to be sort of random...
Got a tip for us?

Hrmmm
Can you post your results?
My MP 3.0 with 6GB, X1900 and RAID 0 Raptors is only 187.89
Fix it 
Boy that stripe size makes a huge difference!
I dropped it down to 32kb and I'm now benching 217.78

Stripe size does indeed make a huge impact. 64k is ideal for the kind of work I do, and that's what it was set to when I ran the benchmark.

This is a better benchmark. And universal to any operating system (Linux, BSD, Win, OS X, anything)
Entering '21' as a value, I got 91.388 sec.
Total calculation(I/O) time= 91.388( 14.327) Sec.
