Awesome, you have tons of kick ass electronic hardware. 16 Gigs of ram.... Dualy Quad Xeons...
and only one hard drive? LOL
With that much hard core gear, I wonder if swap at RAM*1 or RAM*2 or RAM*.5 would make much of difference?
I would be interested to know if it does, if you ever find out whether one out performs another.
Have you considered using the AMD64 port?, or perhaps you have some custom 32 bit stuff that can only run on x86?
