Good one :) Motty, also, can you ogin to VR as I suggested, and install iperf there, and just benchmark from VR to one of the VMs ? Just to see if number differs at all.. I'm not into Xen at all - but I also guess VR for Xen has para-virtualizes drivers inside.... Just for your comparison of emulated vs para-virtualized drivers, my test case: 2 VMs (both on same physical host!) emulated intel NICs - iperf gives arround 1.2 Gbps. Same setup, virtio NICs - iperf gives 8.9Gbps - default iperf options, no tuning nothings...
