[rabbitmq-discuss] RabbitMQ / Erlang not running on all cores?

Tue Oct 22 18:43:30 BST 2013

We're running RabbitMQ 3.0.2 on Ubuntu 10.04 with Erlang 1:15.b.1 on a four
CPU box under pretty heavy load.

Looking at the per-CPU metrics in VMWare, it looks like the beam.smp
process is utilizing only one of the CPUs. One CPU is pegged at near 100%,
while the others are nearly idle.

Is there some sort of configuration switch I've overlooked to enable
Rabbit/Beam to use all the CPUs?

Thanks,

Matt
