I'm running the Windows client on 64bit Windows7. But the Lunatics optimized apps are not available due to licensing issues and that causes me some loss of credits.

Seeing the Linux version of lunatics is still available, the thought came to my mind whether I can run the Linux client + lunatics apps via a virtualization software (such as virtual box) and get more performance out of it...

Is this possible?

I tried running a virtual Linux box at one time as the Linux CPU apps at one time were faster than the Windows versions. However the extra overhead of the VM made it slower overall.

You can't run CUDA on a VM as the OS needs direct access to the GPU's.

A while ago I did some serious experimenting with Linux vs Windows crunchers. I found the Linux GPU apps work well enough, but use more CPU than the Windows versions plus Linux does not seem to handle a busy PCIE bus as well as Windows. A point to consider if you are using more than 2 GPU's

Taking all the above into account, if you make your machine "dual boot" and run a full on Linux cruncher, This is still faster than the stock Windows app.

I tried running a few tests on an Apple Xserve octo core (dual Xeon E5520), using a minimal ubuntu install, versus a Windows7 install, these installs being VMs inside ESXi. For each test, only one VM was turned on, with all 16 threads and all 32GB RAM allotted to the VM.

There was little loss noted, especially if you just simply compare the CPU benchmark tests that BOINC runs.

I'm currently testing similar on a Dell R815 (dual Opteron 6128) running ESXi. Noted very little loss. Except surprisingly the Opteron pales in comparison to the Xeon!
