Unless you've got more than 3 gig of ram I doubt it will make much
difference. 32bit binaries are smaller, and hence faster, but there are a
couple of 64bit only instructions that the compiler might use that could
give some speed benefit.

If you try it, why dont you measure the difference and tell us?

Personally I'd be supprised if the 64bit version is measurably faster, but
I'm often supprised :)
