The initial goal was to see what the performance of intra-node containers are using VPP with both TAPv2 and AF-Packet (veth) interfaces.\r\n\r\n[contiv-vpp.yaml](https://github.com/contiv/vpp/files/2161730/contiv-vpp.txt)\r\n[iperf-server.yaml](https://github.com/contiv/vpp/files/2161734/iperf-server.yaml.txt)\r\n[iperf-client.yaml](https://github.com/contiv/vpp/files/2161733/iperf-client.yaml.txt)\r\n\r\nWhen using TAPv2, I'm getting ~2.1 Gbps between containers on the same node.\r\nHowever when using veth interfaces, I'm only seeing ~20 Mbps. These results are the same when setting `TCPstackDisabled: True` and `TCPstackDisabled: False`. I would have expected the AF_PACKET throughput to be significantly higher than TAP interfaces.\r\n\r\nAlso, I've noticed the CRI-shim has been commented out in a bunch of places in the code. A lot of the documentation still makes reference to it. Is this now deprecated? (if so, I can submit a PR to pull it out of the difference documentation areas)\r\n\r\nThanks."}}
