My point of my message is to understand the exact workload/setup you are using. "dd" was not an entirely obvious choice for CPUBurn and Google didn't provide a lot of website backing this information.

Anyway, now I understand a bit more the workload, a couple of more questions:
    - How many vCPUs are you using in each domain?
    - What scheduler are you using?
    - What is the affinity?

For the test with glmark2: Dom0 (4 VCPUs), DomD (4 VCPUs), 4 PCPUs, no affinity specified.

So, are you running 4 dd (one for each core) in parallel? Are they pinned?

Cheers,
