How many of you are running 64 bit servers?
 
How many of you with leased dedicated or colo dedicated servers are running 64 Bit System? I don't mean that you have 64 bit processors... I mean that you are running 64 Bit Linux.

If you are running 64 Bit.. Have you seen any speed increases that you can attribute to moving to 64 bits and more importantly... have you had any headaches or problems with your 64 bit system?

Which brings me to another question - which FREE 64 OS is recommended?

Centos vs Fedora Core vs FreeBSD?

FlyBoy73 04-18-2006 10:33 PM
I am using (on my new server) CentOS.

We were planning on trying out the 64 bit version of CentOS on our newly ordered server but it will only be running MySQL. Is anyone actually running MySQL 5.0.19 on a 64 bit server? We are still on the 4.0.x line but are looking at whether to install 4.1.x or 5.0.x on this new server. Seems like as good a time as any to upgrade to 5.0.x.

We're using 64bit CentOS. The openssl benchmark says 64bit is faster. I'm not sure how it translates into real world performance. Make sure you use apc and not eaccelerator. EA segfaults on 64bit OS's.

Here are some benchmark results on Dual 3.4 Xeons with 32bit CentOS.
Code:

Same thing with 64bit.

"Higher is Better" :) Well, on the right side of the results..

Thanks a lot for the results.

Erwin 04-19-2006 02:24 AM
Nice results on the dual/dual Opteron! :D

Erwin 04-19-2006 02:25 AM
I'm currently ordering quad opterons and dual/dual opterons and dual xeons in different combos - apparently cPanel (which I like using as it makes life easier for self-management) doesn't like 64 bit OSes - any experiences with that?

FlyBoy73 04-19-2006 02:44 AM
Erwin just voiced the question I should have posed in the opening post - this is a big concern for me as well. We are about to install WHM/cPanel on my 64 bit CentOS 4.1 OS. My server manager told me he has it running well on a lot of other servers he manages and colos (not where I colo) so I just gave the go-ahead to see how it runs on my server, though if it shows any problems I'm not going to be experimenting for good results. I'm not in a time crunch yet to get off my other servers so maybe I can contribute to some testing.

Will let you all know how that goes.

We're using Fedora Core 4 (64-bit linux, dual Opterons, dual core) for our database server...

I don't even have the vocabulary to explain how fast it is.
