Benchmarking with Einstein@Home

Hello,
I am trying to benchmark actual performance of a computer. Since I do not trust benchmarking software for producing a realistic result (any simulation is always more simplified than the real thing and is thus inherently innacurate) and because wasting things, I have turned to distributed computing.
I have been told that Einstein@Home produces evenly sized work units and would hence be suitable for this kind of task. I was hoping for something with huger memory usage to ephasise the advantages of the particular system I am benchmarking, but I guess this will have to do. ;)
Thus I now have comparable data, but nothing to compare it with.
My AMD Athlon 64 3800+, 800 MHz dualchannel DDR2, MSI K9N Platinum, running Windows XP SP2 crunches a work unit in 19250 seconds on average while sitting relatively idle. On the other hand, my Celeron D 2.5 GHz, 200 MHz DDR, Epox, running Mandriva Linux crunches a work unit in 32000 seconds on average, also sitting relatively idle.
If anybody else has any computers sitting relatively idle and is willing to share, I'd ask for some approximate computer specs and the crunching time, to help me do my comparison.
Thanks in advance. :)

All work units are not relatively the same. Each WU (Work unit), has a different amount of computable work within. Such as, a work unit starting with the name h1_0363.0_ is smaller, that h1_1400.0_
The number system refers to the amount of processing time required. From my experience, the number system is not relative. Example, h1_0400.0_... is not half the size of h1_0800.0_...
Currently my computer has all WU's with 0363.0... At times when 98-99% processor ability is being used by the Einstein@Home client, my computer finishes a WU of that size in about 17,580 seconds. Intel Pentium III, 320 MB Ram, 320MB Virtual, WTD (Write to disk) 3600 Seconds Max.
But, if you have the WU name, there is a possibility, that someone else, with the same, or similar size WU, may be able to give you statistics from their system.
Hope this helps!

Hi,
this one of mine is nearly always idle, just watch for the fastest time of a bunch WUs with the same credit.
It's an Athlon 64 3000+ with original 1800 mhz, which now runs with 2523 mhz and DDR 360,6 (180,3 mhz real clock).
It has a MSI K8N Neo4 Platinum Board.

Have fun!
