rabbitmq version: 3.0.2
cpu: 24 cores
memory: 64G
i deploy a rabbitmq service on the server above and do a stress testing ,
use 150 threads for send and 300 threads for recv on 150 queues on the
service, per queue with 1 send/ 2 recv.
the cpu useage is always below 700%, no matter i increase queues and
threads or not.

how to use more than 7 cores in rabbitmq?

i find smp is set to 24:24
[rabbitmq]$ erl
Erlang R15B03 (erts- [source] [64-bit] [smp:24:24]
[async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.9.3.1  (abort with ^G)
