That makes sense. Starting 1000+ consumer connections all at once will 
cause enough work at the broker end that the connection negotiation on 
at least some of the connections might take quite a while. And if the 
consumers are also declaring queues and bindings, and start consuming 
messages the broker has even more work to do and establishing new 
connections will take longer still.
