Hi Talat- The bug was filed against vivid which is no longer maintained. The original submitter had requested certain patches be back-ported to vivid because they supposedly fixed an issue.
The requested patches were back-ported and they didn't fix the issue the submitter purported that they fix. So I wanted to know two things: 1. Does the reported issue still appear in latest releases such as xenial(16.04) 2. If so does this issue appear in the mainline kernel as well? This will determine if the reported issue is an Ubuntu specific issue or if the general mainline linux kernel needs fixing. If you can re-run the tests on 1 & 2 that would be very helpful, but it would also help if you could provide the exact configuration and steps you use so that I can try and reproduce your tests.

We reach 24 Gbps over the VxLan interface while we reach only 4 Gbps over the VLAN interface. Turned out that GRO isn't supported for VLAN over VxLAN. The following upstream commits fix this issue. commit 66e5133f19e901a044fa5eaeeb6ecff4545839e5 Author: Toshiaki Makita <makita.toshi...@lab.ntt.co.jp> Date: Mon Jun 1 21:55:06 2015 +0900 vlan: Add GRO support for non hardware accelerated vlan Currently packets with non-hardware-accelerated vlan cannot be handled by GRO. This causes low performance for 802.1ad and stacked vlan, as their vlan tags are currently not stripped by hardware. This patch adds GRO support for non-hardware-accelerated vlan and improves receive performance of them. commit 9b174d88c257150562b0101fcc6cb6c3cb74275c Author: Jesse Gross <je...@nicira.com> Date: Tue Dec 30 19:10:15 2014 -0800 net: Add Transparent Ethernet Bridging GRO support. Currently the only tunnel protocol that supports GRO with encapsulated Ethernet is VXLAN. This pulls out the Ethernet code into a proper layer so that it can be used by other tunnel protocols such as GRE and Geneve.
