</div>You get one Erlang process per queue. Those are scheduled to run in one or more<br>
run queues (VM queues, nothing to do with RabbitMQ queues). Recent Erlang VM<br>
versions detect how many cores are available on start and create a new run queue<br>
per core.<br>
<br>
How scheduling is performed (that is, how processes are given time to run<br>
and distributed between run queues) is not so trivial to explain and varies between<br>
SMP and non-SMP systems, see<br>
