I'm using ebpf sockmap/redirection to bypass the TCP/IP stack to improve socket communication performance (throughput, latency) between different PODs on the same machine. As concurrent connections or payloads increase, there may be unconspicuous performance improvement or even performance degradation compared to the TCP/IP stack. I have retrieved some performance data, but it does not seem to involve high concurrency and high payloads, I would like to know if community have conducted relevant tests on these scenarios and have any opinions on the poor performance improvement in these scenarios.
