hi,

I running an AuthenticAMD AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ [Family 15 Model 107 Stepping 2] with 2 giga of RAM under Ububtu 8.10 and my CPU benchmarks are very low compared to running under XP.
Benchmark results:
Number of CPUs: 2
766 floating point MIPS (Whetstone) per CPU
1602 integer MIPS (Dhrystone) per CPU

Is this a familiar problem?

When your cpu is benchmarking anything else running, games, internet, email, moving the mouse around, whatever, will slow it down. About once a week Boinc benchmarks on its own. You an also make it do it manually thru the Boinc Manager, the icon by the clock. Open it and click on the Advanced Tab at the very top and then go down to Run CPU Benchmarks, click on it and then DON'T TOUCH THE MACHINE and see if the numbers are better. People with Boinc only machines will always have 'better' numbers than those that use theirs for other things too.

Basically don't worry too much about them, they can change quite a bit from test to test depending on what else is running at that moment. The RAC is what I watch, it is like a speedometer. It shows how fast you are crunching right now. It can vary radically though due to things beyond our control. If the projects servers have problems the RAC can suffer, if your wingman fumbles his crunching your RAC will suffer, etc, etc, etc.

I believe the crux of the question was whether others have compared benchmarks of the same machine running under Windows, and then under Linux.

As Mikey says, your actual credits (at least at Rosetta) are not directly based on your credit claim (which is in-turn based on your benchmarks) anyway. So, the difference isn't hurting your granted credit on Rosetta.

Rosetta Moderator: Mod.Sense

A few things, first since this computer is an unused one that I have laying at home, I decided to experiment on it yesterday - this is why it is running Linux.
BOINC is the only program that is installed on it - the benchmarks did improved slightly with me not touching the mouse.
The REAL RAC is from a different computer running Rosetta 24/7 and not from the new one.
If there is anyone here using a system similar to mine (Ubuntu 8.10, AMD, 2 Giga RAM) I would like to know if these benches are OK.

This guy fixed it himself and explained what he did.
