[erlang-questions] gen_udp:send and concurrent access to the same Socket

[Bengt Kleberg]

Greetings,

Any processes can send on a socket. Only the owner can receive on a
socket.

>From a design point of view it would seem better to me with a single
process that does all the sending. If that is not possible given your
performance requirements (measure) you can send from all processes.
