Why there are high deviations in the networking speed? 1st, iperf is a very unpleasant measurement suite if we speak about virtio-net performance, small packets testing with pktgen may reveal much more, as I told recently; 2nd, there should be neither many gbits/sec value if VMs are colocated (since iperf produces bit/s output) or flat characteristic if throughput was limited by media speed. Since iperf consumes not much of CPU, it should perform well enough even on a single-cpu VMs, if no other limitations are involved. Though I know that there is no difference at the gigabit speed, network results worth to be scrutinized a bit more.
