inetd uses stdin/stdout to communicate with the daemon and have to
launch one instance for each client connecting. systemd.socket pass a
regular listening socket on first connection to the daemon and the
daemon can then serve multiple clients. It is simple to convert an
existing daemon to systemd.socket and it doesn't come with a performance
impact. It can even simplify some aspects of an always-running daemon,
like reloading without impacting the traffic.
