Yes. Exchanges are just routing logic; they don't need to be factored 
into load calculations. Queues on the other hand are stateful and a 
single queue can only use one CPU core - so splitting the load among 
queues is valuable.

You would (obviously) also want to split the connections across nodes. 
And it certainly helps to have as much locality as possible (i.e. 
publishing to and consuming from queues on the same node).
