Dear Monks:

I am working with a couple of Apache/mod_perl applications that run on 32-bit and 64-bit platforms. The versions that run on these to platforms are identical as far as the code base goes. Both are platforms are Red Hat Enterprise (same version -- different architecture).

My question stems from my lack of understanding of 64-bit architectures in general.

I am having some difficulty understanding why the Apache processes on the 64-bit machine are some 60% larger resident memory-wise. This huge difference in memory use is causing some rather bad performance on the 64-bit platform.

Is anyone aware of anything in general that I should be aware of when moving Apache/mod_perl applications to 64-bit platforms?

Thanks in advance,

Matt
