Total throughput capacity but not throughput of a single queue. If you add more nodes
and distribute queues between them roughly evenly, then yes.

Note that if you mirror a queue to *all* cluster nodes, adding more nodes
increases overall load of the cluster. Most of the time, though, it's perfectly
fine to only mirror to a subset (say, 2-3) nodes.
