A named pipe (fifo) would be an interest to test too. I believe theyre a good bit faster than a unix socket.

My recollection from Advanced Programming in the Unix Environment is that unix sockets are actually often faster than named pipes:

You got me curious; according to a quick search, that seems to hold up according to this more recent post (which doesn't note the OS, annoyingly):

I'd be interested in more robust data here.

IIRC for most packets, UDS are actually faster (not by a massive amount) than named pipes: https://stackoverflow.com/questions/1235958/ipc-performance-... and this advantage increases with packet size (from my own testing).

TIL! Thanks for the link.

Have only seen the other way but shmem with a spinloop should be faster.
