I still don't think there's a performance improvement of going with 64-bit
on the same system unless you have some very particular needs (>32-bit int
math maybe, huge process memory space).  In fact your message has made me
expect it to be worse.  All that extra resident space is more bits that
have to be shoved across the bus, etc...  As we've seen with IPv6, adding
more bits that you aren't using impacts performance...
