Hi XDP experts, Recently our team is trying to use AF_XDP to improve our socket performance in media servers, which will spend 50%+ CPU resources in socket send and recv functions. However, we still hear the different voices that VPP/DPDK is one better option. I read many documents, and found that if applications don’t attach packages, DPDK is better, and if applications will process packages, XDP will approach the performance of DPDK. For our applications, servers will create hundreds of sockets to receive h264 streams, and send out these streams into the different sockets. Based on the above descriptions, do you think which solution is better one? Another question is about AF_XDP usage: by this document, https://www.kernel.org/doc/html/latest/networking/af_xdp.html We need to use ethtool to map the ingress port and egress port, but our application can create socket connections randomly, how to use af_xdp to resolve this problem.
