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-email-jesse@nicira.com/

But, unfortunately there are no stats present in that discussion.

Thanks,
Ronak
