Sorry, what's brawndo? (Searching only gives me movie results?)

We started out discussing AF_UNIX vs. AF_INET6. If you can conceptually use something faster than sockets that's great, but if you're down to a socket, unix domain will generally beat inet domain...

You can do some pretty crazy stuff with pipes, if you want to do better than unix sockets.

Sure, but setting up a piped session with a pre-existing sidecar daemon can be complicated. You either end up using named pipes (badly behaved clients can mess up other clients’ connections, one side has to do weird filesystem polling/watching for its accept(2) equivalent), or unnamed pipes via a Unix socket with fdpass (which needs careful handling to not mess up, and you’re using a Unix socket anyway, so why not use it for data instead?).

it's what plants crave! it's got electrolytes.
