I downloaded the chess program (Windows) and ran it as is
on Windows-64 and here are the results:

How did they get 155K? I didn't even recompile/relink using
a 64-bit compiler!

My machine is a 2 Ghz A64 with 1 MB cache compared to the 2.2 Ghz
model with 512 KB cache that they tested. I'm running my full complement of day tools including Thunderbird Email, Antivirus, emacs, tarantella and FireFox.
