Confusion about results

Hi there,

I am evaluating several benchmark solutions for my university at the moment and I also used Geekbench 2.4.0 in the tryout mode for this case.

I ran it on the same hardware with different operating systems and got kind of confusing results. Please see the results in your online comparison with the following IDs:

1313919 (Debian 6 native, fully patched)
1302421 (Windows Server 2008 R2 native, fully patched)
1302417 (Debian 6 running on VMware vSphere 5.1)
1302499 (Windows Server 2008 R2 running on VMware vSphere 5.1)

What confuses me is the big difference I can see on the results. In my opinion with a CPU benchmark there shouldn't be such differences resulting only of running different operating systems. What confuses me even more is the fact, that Windows native is much slower than a virtualized Windows.

Is there any logical explanation for this phenomenon?

   Thanks for your message. What power plan are you using when running Windows Server 2008 R2 natively? You can find the current power plan here:

   Control Panel > Hardware > Power Options
   

   Thanks,
   John

   Hi John,

   I changed the power plan to "Höchstleistung" (highest performance). The results do make much more sense now. Thanks for your input.

   I'm glad my suspicions were correct! Let me know if you have any other questions and I'd be happy to help out.

   Best,
