Hi,

What about mature projects with libevent and multiple threads you can
take a look at libevhtp in particular (but this is for TCP):
  https://github.com/ellzey/libevhtp/blob/develop/evthr.c

It uses socketpair() to distribute jobs between threads (AFAIR).

Also there already was similar question, you can read it too:
  http://archives.seul.org/libevent/users/Mar-2016/msg00007.html

And I'm voting for not using threads until you really need them too
(and indeed sometimes syncing primitives can make it slower then
single-threaded program). Plus what you are describing here (every
thread use it's own port) can be implemented with spawning multiple
processes (but maybe it won't be optimal choice indeed).

Hope this helps.

Cheers,
Azat.
