Every "real-world" test with 64-bit builds I'v
done is so slow its not even usable in my view.
The larger code causes things to fall out of the
cache faster, and caching is more important to
performance than 64-bit processing.
Just because 64-bit is there doesn't mean you
have to use it or should. If you don't need more
than 4GB then its just plain stupid to use a
64-bit OS, at least with the current state of
