Each queue can only use one core on your machine, so having multiple 
queues will definitely help.

Also, using more than one queue from the start will make it easier to 
scale horizontally.

400,000 msg/s is quite a lot. Turn off all the features you can (acks, 
confirms, complicated routing, persistence) and parallelise as much as 
possible.
