64-bit architecture a memory hog for Apache/mod_perl?by Booger (Pilgrim) |

Booger has asked for the wisdom of the Perl Monks concerning the following question:
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
