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.
Really? I find that odd. I didn't notice any drastic change (though I didn't do any hard core testing) between 32-bit and 64-bit 4.4 on my quad-core boxes running the 9550SX. However, that could be just me. Apparently, I am just a young Skywalker in terms of tuning these new-fangled 3Ware cards and dealing with partitions/filesystems/etc. Without Josh Baker-LePain's kind advice, I'd probably still be wrasslin' with it. :)
