...ata copy in this case. Test result: Before this patch: VM1 to VM2 throughput is 9.3Mbit/s VM1 to External throughput is 40Mbit/s CPU utilization is 7% After this patch: VM1 to VM2 throughput is 9.3Mbit/s Vm1 to External throughput is 93Mbit/s CPU utilization is 16% Completed performance test on 40gbe shows no obvious changes in both throughput and cpu utilization with this patch. The patch only solve this issue when unlimited sndbuf. We still need a solution for limited sndbuf. Cc: Michael S.
