Re: [opencontrail-dev] [Users] dpdk vrouter performance

If the VM does not use a DPDK application, there are VM exits when forwarding packets, which kills performance. Also, segmentation/receive offloads (GRO, GSO) are not supported by the DPDK vrouter in 3.0 (supported from 4.0), so that would also reduce the TCP throughput. Raja From: Users
