CPU benchmarks for Opteron 285 low?

[sbalfour]

Here is my CPU benchmarks run on a second server I'm bringing up:

Sat 13 Jun 2009 01:34:30 PM PDT||Benchmark results:
Sat 13 Jun 2009 01:34:30 PM PDT||   Number of CPUs: 4
Sat 13 Jun 2009 01:34:30 PM PDT||   835 floating point MIPS (Whetstone) per CPU
Sat 13 Jun 2009 01:34:30 PM PDT||   2474 integer MIPS (Dhrystone) per CPU
Sat 13 Jun 2009 01:34:31 PM PDT||Resuming computation

The server specs are:
MSI K8N Master2-FAR
2xOpteron 285 (2.6ghz)
4x1GB DDR2 800
Nvidia 7900GT
Kubuntu 8.10 (32-bit)
Boinc 6.2.12 (prerelease)

Elsewhere, I read the Opteron 285 running Windows had benchmarks of 3605/10979.  That's 4
times what I apparently have.  I just completed a Seti_enhanced WU in 9hrs, as a shakeout
(standard Berkeley client).  Is there anything wrong here before I start on optimized apps?

Your opteron is 64bit capable right? For seti crunching it would be better if you would switch to a 64bit OS. Current astropulse apps are much faster in 64bit.
Also boinc 6.2.12? Is this correct? Right now we are up to 6.6.36.

Boinc benchmarks don't mean much.
I don't know the speed of the standard client but 9 hours seem a bit too much. Anyway, you can start using the optimised ones any time you like.

Nine hours is definitly too much. Are you sure you were running without kubuntus powersaving enabled ?
And is there a good reason to use a prerelease BOINC client, especially on a server ? No. The next linux release after your version was 6.2.15, maybe that is also part of the too low benchmark performance you have.
Don't know if you need a 64bit linux version, as you say it is a server, so you won't change your setup too often.

My server is a full tower that sucks power from a dedicated 20A wall socket, and has no UPS at the
moment.  So power saving shouln't be enabled.  Neither kpowersave app nor powersaved appears to be installed, and I have no battery icon.    Remarks about my pre-release Boinc version and  32-bit Kubuntu are taken under advisement - I've only had the server running since
midnight today.  I installed the optimized Seti app and cobbled the app_info.xml file to supply the
optimized executable for both versions 528 and 603.    However, it seems to be ignored - new
seti_enhanced 603 tasks start, and pick up the old stock executable.  How did that happen?

Also, I installed sysinfo and it returned CPU Frequency = 1000.000Mhz (!)  Seems obvious that I
check that explicitly, but I didn't. I've never seen it be other than 2.6ghz. So, where does that get crippled in Kubunu?

Can you post here your app_info.xml?

Check your BIOS if you've active some power saving options. Post here what cat /proc/cpuinfo (from one core) and cat /proc/acpi/processor/CPU1/info give you.
