How do you decide the necessary backlog length for listening sockets?

I don't think you can set that manually, the kernel does that for you.

The road forward for systemd Posted May 28, 2010 10:33 UTC (Fri) by michich (subscriber, #17902) [Link] Looking at the code... It uses SOMAXCONN by default (src/socket.c:socket_init()) and it allows overriding it in the config file with a Backlog=... line (src/load-fragment.c).

As already pointed out we set it to SOMAXCONN by default, which should be a very good value for (almost?) all cases. And to cover other cases, we allow you to override that in the .socket file.
