Our new dual CPU workstation, 2x Xeon E5530 (Nehalem), 8GB RAM, 3 SAS disks in hardware RAID 0 configuration.

These are benchmarks of newest WRFEMS bench NMM and ARW simulations:

With penryn binaries instead of core2 it is even faster!

Update... I have since did this same benchmark at 8 minutes 5 seconds. The difference is that I changed DECOMP to 1 from the default of 0.

just one question
CPU Speed (MHz) : 800.000
why this is 800 mhz and not 3200 mhz???

Excellent results from that cheap CPU! Is it overclocked?

Uhmmmm 800MHz... don't know, what is output from this command?

Code: Select all

cat /proc/cpuinfo | grep MHz

Cool 'n quiet. When the script measures your processor speed, it is underclocked to save energy. When you apply a load, it revs up to full speed. Turn off cool n quiet in your bios, and you will see it report the proper speed... but you will be wasting energy during idle times.

But that is cheating because all benchmarks has to be performed in the same conditions (same domain handling)... ;)

You are actually right... if you want to properly see the difference in system speed, you need to keep the test standardized. DECOMP = 1 is not baseline.

But if you want to speed up your operational runs... I recommend playing with that DECOMP value. You can see it made a dramatic improvement in my benchmark run.
