Overall performance depend on many things: CPU speed, number of CPUs,
memory size, I/O, especially, virtual memory paging, network interface
64bit machines come with better capacity except
cpu computation speed! 

Have you ever tried 64bit Windows desktop or laptop over 32bit machine?
This will tell you exactly. If your application is data intensive, big
over 4GB can work better with reduced I/O operations! Database servers
or WS that support session information of thousands of users over long 
period of time, having big memory improve performance.

If you have studied computer science and engineering basics, you shouldn't
be arguing about slowness of 64bit crunchers!

Otherwise 64bit machines suck! That;s why 64bit Windows is not 
popular. I don't them many shops selling!
