I have MySQL running on a 32-bit RHEL box. The server itself has 4GB total memory with 2GB allocated to MySQL.

I would like to know the max amount of memory I can put in the box and how much of that I can allocate to MySQL.

I have heard both 2GB and 4GB as the per-process-limit on a 32-bit OS...

Ultimately I'd like to know if I can increase the memory for MySQL without upgrading to a 64-bit OS.

Running some 32 bit applications on a 64 bit OS could actually be slower. The additional overheads in running 32 bit software in 64 bit mode could cause a slight degradation in performance.
