You're right, I hadn't benchmarked this before, but the impact on network throughput is significant.
I still don't know if this a KVM or Kernel issue, I'm also running multiple Ubuntu systems on VMWare ESX, all with SMP and they don't show this issue. So the issue seems to exist in KVM in this case and not the Linux Kernel. But... it could be that VMWare has already addressed this issue with some nifty workaround in their hypervisor, and it still is a linux kernel problem.
