Oops, I did not notice the # of cores in your table.

Can you clarify a few things?

 * How do you run your benchmarks. Do you use PerfTest [1]?
 * What’s the average message size?
 * Are you sure messages are always routed?
 * Do you see messages piling up in the queues?
 * Can you post ps aux | grep beam output? (this will display Erlang VM flags)
