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 ?
Note: All my servers are 2GB RAM or less.
As usual, it depends. All my cluster nodes are x86_64, and I've seen anywhere from 10-50% performance gains with some codes going from i386 to x86_64. These are mostly commercial codes -- FEM (LS-DYNA) and Matlab.
