A well written C mux is absurdly performant. I was handling thousands of requests per second with efficient hand rolled binary protocols in the early oughts when I could make UDP work, which I could since it was an intra datacenter app and a super lightweight exponential backoff retry scheme on the client side was entirely adequate. “Modern” network programming is hilariously inefficient. I think games are the only mass market exception since that’s the one area where optimal network performance affects pleasantness. Gamers used to speak of netcode almost reverently.
