Here is my evidence that 64-bit in Linux is faster than 32-bit in 
Windows...previous experiments on 32-bit machines indicated very little 
difference between Linux and Windows:

And here's how I did the install:
http://www.swarm.org/pipermail/support/2008-September/015763.html
(That message doesn't say it clearly, but install the 64-bit version of 
everything, especially gcc.) I've been using this setup heavily ever since.

(My very limited understanding is that 64-bit addresses let the machine 
get stuff in and out of memory faster. One interesting little side 
effect is that if you output an object's address as an identifier, 
*some* of the addresses will be twice as long as others.)
