The library is built on top of uWebsockets which is fairly well-known as being highly optimised and performant, especially if you skip the Node.js wrapper and use the underlying C/C++ lib directly. Does anyone know what tradeoffs or different performance characteristics one would expect to see from e.g. Elixir/Erlang vs uWebsockets?

Elixir/Erlang are surely slower but the BEAM is a fantastic runtime and compensates with fault-tolerance and predictable performance. I know I prefer my server to be as responsive at 1 million connections as at 1 hundred.

How much slower though, I think we’re talking everyone getting the message in a Phoenix channel in < 100ms?
