So I'm going to have to stick with 32 bit machines for a bit longer while we 
find alternatives for some com's we're using that don't work on a 64 bit 
platform.

Here are the average page load times from 3 different machines:

2x single core opteron 246 (2Ghz / core):  251ms
2x Dual core Xeon 5160 (3Ghz / core):  196ms
2x Quad core Xeon 5540 (2.53Ghz / core):  261ms

We're running database servers on similar Xeon 5540 machines and the SQL 
performance on those boxes if far better that what we would get with the 
Opteron's or Xeon 5160's.

Does anyone know why requests run on the older generation xeon 5160 would be 
20% faster than the current generation 5540?  Is the speed of a ColdFusion app 
purely based on clock speed in anyone elses experience?

Thx,

John
