mySQL comes in 32-bit and 64-bit flavors. I have a 64-bit OS (OS X 10.8.) What are the advantages/disadvantages to running 32-bit vs. 64-bit mySQL on my 64-bit OS?
p.s. I'm going to use mySQL with MythTV so my data needs should be small

x64 is what most people with new installs should be using. It is able to address more than 4GB of memory.
If your data footprint is tiny, it shouldn't make much difference, but there's no real reason not to use x64 if you're already on a x64 OS.
