You are only using two cores at that point though, and no hipe 
compilation. Add a "-x <n>" parameter to MulticastMain to increase the 
number of producers, which should end up utilising more cores. And see 
the hipe_compile rabbitmq.config entry 
(https://www.rabbitmq.com/configure.html#config-items) for enabling hipe.

I can get 90kHz (for 10000 byte messages) w/o hipe on my machine that 
way, and 100kHz with hipe. And that's with MulticastMain occupying 3 of 
the 8 cores, so when running that on a separate machine I'd probably see
