Ah, good, actual science this time instead of apples-to-oranges. :)
Thank you for doing
CPU Core at 100% for entire test, x64 code is ~10% faster than x32 code.
So; IO bound things 32/64 doesn't matter so much; but compute bound,
through data already in memory gets significant improvments because of
addtional general purpose registers and optimal calling conventions for
things of few

One cannot tell, unless comparing profiles of both.
One thing to remember is that
Nice Keith,
and very topical as well as being informative. Note a couple of things that
got my curiosity chip activating:
*subquery in result set* test produces interesting outcome with the 64 bit
version bucking the trend. Any ideas there?
Also it would appear *select* clauses demonstrate an abo
