Well, on a 64bit architecture it makes sense to use 64bit os and therefore 64bit applications. Especially if the application has to handle large amounts of data and/or memory. Sure, a "hello world" wont be faster enough for being noticed by anyone on a 64bit or 32bit. But if you have a large database server or you have lots of data to be crunched you dont want to hassle with 32bit boundaries if you have real 64bit power. ;)

I would be absolutely shocked if someone could find a real-world performance difference for DBMail running in 32 or 64 mode on the same chip. We just don't do enough integer calculation to matter a hoot, I believe. The underlying database may perform differently. The operation system may perform differently. But I strongly doubt DBMail will, on its own, be any different. (The former two may have non-trivial differences, especially if you have more than 4GB of RAM and you need those crappy PAE modes to get at it from a 32-bit OS).
