How are consumers and producers distributed?  Also, how about the
conduitSubscriptions setting on the network connector?

If conduit subscriptions is false, every consumer added to the network leads
to a cross-network consumer from that broker to all the broker's peers; and
each broker then propogates the subscription to its peers - that's how
dynamic routing works in ActiveMQ.

One way to see this is to look at the number of consumers registered on the
Topic for each broker.

Also keep in mind that each separate Topic subscription gets a copy of the
message.  So, one message going to 1000 Topic subscriptions results in 1000
copies of the message.  Try enabling conduitSubscriptions on the network
connector so only 1 copy of a message crosses between any two brokers:
