4 Gigs per process is a bit more accurate I think, right?... which is
still quite a bit relative to a "usual" webserving environment.

I would say to the OP that 32 bit is most likely still more compatible
across the board, especially regarding 3rd party libs and such. However, 
there are some
benefits with 64bit.. but maybe not as many as one would think initially...

- More (virtually unlimited in todays standards) memory space.
- Perhaps some performance improvements based on the potential to
handle more information per clock cycle.

What does this come down to??  In most every day web serving,
you won't notice a difference and you may run into compatibility
problems. Then again, you may not. Your unique uses may vary
the results.

I would weigh in the platform that you are running
Apache on and then take a look at your valuable mods/3rd party apps
that you may need to make sure they are compatible.
