Running a 64-bit OS on a system that's working fine on a 32-bit OS,
assuming you have less than 4G of RAM, will probably not produce a
noticeable speed increase.  64-bit binaries are a bit larger on
average, so some aspects might be slower.  

PAE kernels are a lot slower with >4G of RAM regarding memory
operations, though, which is why everyone is asking how much RAM you
have.
