[erlang-questions] [99s-extend] How to broadcaset with ranch?

[Max Lapshin]

It is important to understand that if you use gen_event to register event
handlers, than all event traffic will flow through one single process.

If you have 100 messages per second and 10 000 subscribers, than one single
process (one single core) will send 1 mln of messages per second.

If you register subscribers in public named ets table, than each producer
will send only 10 000 messages, which can be distributed among cores.
