Does anyone have access to one of the new Mac 
Pro's?  It would be interesting to see how they 
perform, and they're fairly reasonably priced for 
a dual quad-core Xeon box.  It would be best if 
the test was done under both Mac OS X, and Linux, 
I've a bad feeling I know which would win. :^(

X 10.4.11.)

Well just for fun...  I VESTed it.  Here is what 
I get from a Compaq XP1000 which has a 667Mhz 
21264 CPU, 2GB RAM, and is running OpenVMS 8.3.
