Update GH actions to OCaml 5

Add buffering of outgoing messages Sending each message in its own TCP packet isn't very efficient. Note: The Prometheus metrics `messages_outbound_sent_total` and `messages_outbound_dropped_total` have gone. They weren't very useful and we no longer know the number of messages by the time the connection is dropped (could report dropped bytes if needed though). $ dune exec -- ./test-bin/echo/echo_bench.exe echo_bench.exe: [INFO] rate = 18466.209374 # Before echo_bench.exe: [INFO] rate = 59655.912455 # After

Simplify message writing system Instead of spawning a new flush fiber if one isn't running, just keep one around at all times. This is simpler, makes the traces cleaner, and will probably help with buffering later.

Clean up benchmark

Update MDX

Ignore errors trying to set `TCP_NODELAY` This happens with non-TCP sockets. Reported by Patrick Ferris.

Set TCP_NODELAY to avoid Nagle's algorithm Should probably buffer up messages instead, but this solves the immediate problem.

Avoid MDX 2.4.0 It executes code while including it!

Update to new tls-eio API
