As such running Snow Leopard with the 64bit Kernel isn't going to make much of a difference in performance.
64bit kernel allows better randomisation for ASLR thus improving security, there is a performance penalty running 64bit on a 32bit kernel; there are many other benefits outside simply addressing more than 4GB of memory.
