   Should be typical on which processor?

   A 64-bit binary in a Sun Sparc is not faster than a 32-bit binary.
The same is probably true in a Macintosh.
   In the AMD64 there's a speedup when running 64-bit binaries, but
that speedup has basically nothing to do with the amount of bits.

   This is based on what? Which OS?

   Current hardware probably puts a limit and 2^64 bytes of RAM
is (in current hardware) not possible.
