Running 64 bit sles9 on an Opteron really opened my eyes.. it
screams.. I use it wherever possible.
So far i've only done single CPU however.. the real boost of Opterons
happen with 2 or more processors so you get the data channel going. (
and you need sperate RAM for each CPU ) . Hoping to do a good DB server
test someday soon.
We also aahve 64bit SLES on Intel ( 64 extensions ) for a new backup
media server.. the server also does encryption before shipping to tape
and the 64bit there seems to help really move things along.. at least
our tests seem to show that. (and in some test cases running
encryption is even faster than without.. which doesnt make musch sense -
unless possibly the data simply flows better like that to tape or
something ?? )

I don't have your answer; I have a question.
How much faster/slower is an Opteron running 32 bit code vs. 64 bit
code?
It's not clear to me whether your server will be working hard enough
that you care, but I'm curious.
