Hi, Dario:

Thanks for the reply.

The CPU i am using is i7 X 980 @ 3.33 GHz,

each core has dedicated L1(32K data, 32K inst) and L2 (256K unified) cache, all 6 cores share a 12MB L3 cache.

I pinned Dom-0 to core 0, and Dom-U to core 1.

It might be worth switching those around -- e.g., try pinning domU to core 4 / 5, or try pinning domU to core 0 and dom0 to core1, just to rule out some kind of strange NUMA / microarchitecture effect.
