I have so far avoided using the x86_64 distro, sticking to 32 bits on all my servers.
My question for all using the 64bits distro is: is it really worth it ? What kind of applications are you running, and what kind of _real_ gain did you have ?
apache, postfix, mailman on centos-4.4 data throughput to and from hard disks via 3ware9550SXU-4LP is much faster than with the same hardware and a 32 version (about +40 to +50%, I tried it). It's definitely worth it but it certainly depends on your hardware.
First I got a bit confused about the lib64 directories and the ability to have 32 bit packages, but once you get used to it, it's easy to handle.
I'll stay at x86_64.
Note: All my servers are 2GB RAM or less.
4GB.
