I'm with you, David, it might be a multitude of factors.  In my article
for next Monday, I point out that we're talking about a 2004 i5 595 and
a 2000 model 840, so the differences can be far more than just the JVM.

At the same time, I guess my point is that, no matter the reason, if the
numbers have jumped that high then there's a good chance that my
WebSphere applications will run a LOT better on the i5 boxes.
