It would be some change in virtio-net driver that may have improved the latency of small messages which in turn would have reduced the bandwidth as TCP could not accumulate and send large packets.I will check out any latency improvement patch in virtio_net. If that's the case, whether it is good to have some tunable parameter to benefit both BW and latency workload? Shirley
No, we need it to work well automatically somehow. -- MST
