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?

Erwin 04-18-2006 10:28 PM
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.

markA4 04-18-2006 11:20 PM
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.

"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.

kerplunknet 04-19-2006 07:31 PM
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.

Erwin 04-19-2006 09:48 PM
The problem with Fedora is its short lifespan of a few months vs a few years for the others.

Erwin 04-19-2006 09:49 PM
Anyone using Debian with a 64bit kernel?

Erwin 04-21-2006 12:18 AM
FWIW, I've decided to go with FreeBSD for my new servers.

It is very, very easy to upgrade from older versions of Fedora. It's pretty much:

rpm -ivh fedora-new-release-here.rpm

yum upgrade

Reboot the server and done!


I have had bad experience with CentOS, for the record.

FreeBSD is a VERY good choice if you know how to administer it.

Erwin 04-21-2006 03:00 AM
I'm a RH7.3-9, Fedora Core 1, RHEL2and3 kinda guy myself. FreeBSD will be new, but it looks robust and upgrades using the port system looks enticing! Part of the potential issue with Fedora is that it has the impression of being a test OS for commercial RHEL, and as such, is bleeding edge and may be unstable/unsecure.

dan35 04-21-2006 05:26 AM
yeah, FreeBSD rulezzz :p

Yes for a while but I stepped back to K7 after it caused me too many headaches such as certain apps requiring cross compile environment etc.

Erwin, what version of FreeBSD are you going to use? I want to use FreeBSD 6 (64 bit) with Cpanel, however Cpanel says FreeBSD 4 64 bit is the latest they support.

I NEED Cpanel.

I am currently running CentOS 64 bit without issues and am trying to figure out which way to go when I buy a new box next week.

FlyBoy73 04-25-2006 06:15 PM
I am running CentOS 4.1 w/ WHM/cPanel in 64 bit without a problem so far. I know my server manager did some tweaking but he said they have been running / managing 64 bit servers with cPanel now for a few months without any problems. I'm guessing they have resolved the issues themselves since a lot of people have been having bad experiences with 64bit and cPanel

BrentW 04-25-2006 06:49 PM
Athlon 64 / Fedora

Erwin 04-26-2006 07:54 AM
I'm going to use FreeBSD 6.0 - I'm going to go without cPanel this time round. :)

ramprage 04-27-2006 12:01 AM
Don't use Cpanel and a 64 bit OS you'll run into all kinds of problems.

scottct1 04-27-2006 12:20 PM
I have been running CENTos 64 Bit and Cpanel for about 6 months now with no issues.

ramprage 04-27-2006 04:57 PM
Lucky, what version? The last time I tried it it was recently out, so maybe they've fixed most of the issues with it. We were using RHEL

Erwin 04-28-2006 12:38 AM
Even with Centos 64 cPanel has some bugs - at least what I've been told.

Please keep us updated on how this goes for you Erwin. I've always been a BSD fan and I'm intrested in how well it will preform on your site. :)

Sure will. :)

eva2000 04-28-2006 06:55 AM
if i had to go 64bit i'd try SUSE Enterprise Edition - probably the best one for 64bit hardware driver compatibility as that would be one of the top issues with 64bit OSes

Dude, it's still not open source. :) Well, it is, but commercialised. :)

FlyBoy73 05-01-2006 03:15 AM
ATM, the only issue we have run into is getting MRTG to install & run properly. Have a TT submitted with cPanel on this. Other than that.. Running fine still.

Erwin 05-02-2006 10:43 PM
My servers are running FreeBSD 6.0 AMD64 without any problems on Quad Opterons and Dual Processor/ Dual Core Opterons. Initially we had the wrong kernel compiled so only 1 CPU was recognised, but this was picked up quickly - we now run the 64bit SMP kernel, and the forums have never been faster.

FreeBSD is an awesome OS - the ports system is easy - install portmanager and you can easily install ports using single commands - say goodbye to problems with rpm dependencies. :) It's also fairly easy to customise, and is secure.

I documented everything I did to set up a FreeBSD server, so if anyone wants help, let me know. :)

Also, I'm running Lighttpd instead of Apache - this is a fantastic webserver, much leaner than Apache, and is fast! It also load balances php by running php as separate processes - you've got to try it out to believe the difference in speed and reduction in server loads.

yeah that's the point for wider 64bit hardware driver compatibility it would probably save alot of hair pulling sessions :)

Erwin 05-03-2006 09:43 PM
We did pull our hair out when we had to try a few RAID cards until one worked with FreeBSD. ;)

dbembibre 05-09-2006 06:40 AM
I have Dual xeons 2.8 with scsi and 2 gb of ram, and planning in a shrort time move all my forums to a new quad opteron.

PixelFx 05-09-2006 04:38 PM
I'm running my sites on dual core amd64 4400+ & 3500+ out of my studio, so far so good. I'm using Apache 2.0.58, php 4.4.2, and mysql 4.1.19 on xp pro other than needing to setup ioncube it seems to be running good.

titodj 05-16-2006 05:33 AM
Quad Opteron (DualCore) 265
120gb sata raid + 120 sata backup drive
CentOS 4.3
Cpanel
And no problems so far...

kerplunknet 05-17-2006 07:10 PM
Some people may get confused...

You can have 64-bit CPUs (x86_64), but run a 32-bit OS. (x86)

I wonder how many people are running true 64-bit systems.

SFGHQ 05-21-2006 04:21 AM
Just for the record, if you are going to run 64bit CentOS, be sure you recompile the kernal.

The kernal it comes with has a nasty bug that causes it to eat up swap for memory usage over 400mb, even if you have more RAM available. Caused me lots of trouble.

I'd probally run a 32bit os with a 64bit processor.

titodj 05-23-2006 07:55 AM
Jeje I think you just give me the answer to my ram usage problem...
I was clue less
