The server is running on a 4-core Cortex-A53 at 960MHz (an Allwinner A64 SoC). I didn't think about generating a TLS certificate in advance, so the CPU time includes roughly 2s spent generating an RSA key. No UDP mux: user 20.15s, system 15.05s. UDP mux: user 21.61s, system 19.05s. I find the increase in system time suprising, but since I didn't repeat the test, it might be an experimental error. I've generated a CPU profile, and the time spent in the UDP mux is negligible, on the order of a fraction of a percent. I think we may conclude that the overhead of UDP muxing is negligible. -- Juliusz
