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.
