As I explained, using basic.qos actually hurts performance, but can 
produce *more consistent* performance.

Note that in general when simultaneously sending to and consuming from a 
queue, the performance can fluctuate. That's because the queue is a 
synchronisation point - it can only deal with publishing *or* 
consuming/ack'ing. The balance between the two is down to scheduling and 
can shift over time.
