I have nothing else overlapping it. Dave, any news on this? Shirley, I note that your final commit message did not contain this information from your original version: Tests have been done for small packets, big packets and mergeable buffers. The single netperf TCP_STREAM performance improved for host to guest. It also reduces UDP packets drop rate. The netperf laptop results were: mtu=1500 netperf -H xxx -l 120 w/o patch w/i patch (two runs) guest to host: 3336.84Mb/s 3730.14Mb/s ~ 3582.88Mb/s host to guest: 3165.10Mb/s 3370.39Mb/s ~ 3407.96Mb/s Thanks, Rusty.
