Greetings, I am running into performance issues passing TCP traffic through VPP. My network of docker containers achieves ~25 Gbps using iperf when VPP is disabled. When running VPP on the edge nodes of my network, that same throughput throttles back to ~300 Kbps. I can see the TCP packets traversing the nodes of the VPP tree using 'pcap dispatch trace', so I know the traffic is moving through my VPP instances. I do not see obvious errors, though pcaps at my client/server end points (outside of VPP) are unhappy (lots of fast retransmits, dup ACKs etc). I do not have such issues when sending UDP traffic. Is there any additional configuration or default configuration that could be interfering with TCP over VPP? (not currently using DPDK but planning to enable that soon).
Regards.
