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.
