Can you provide some numbers to illustrate what the slow down is?
Below are some sample test numbers collected by our perf team. Test socket & msg size base using only gro 1VM 14vcpu UDP stream receive 256K 256 bytes (packets/sec) 217.01 Kps 187.98 Kps -13.37% 16VM 2vcpu TCP stream send Thpt 8K 256 bytes (Gbps) 18.00 Gbps 17.02 Gbps -5.44% 1VM 14vcpu ResponseTimeMean Receive (in micro secs) 163 us 170 us -4.29%
In the past as well similar test was done. See https://patchwork.ozlabs.org/project/netdev/patch/1308947605-4300-1-git-send...
But, unfortunately there are no stats present in that discussion.
