I think that is itself quite an important point in these sorts of 
measurements. As the basic.publish command is asynchronous with no form 
of acknowledgement, what a publish rate actually measures is vague and 
client specific.

A more meaningful result is often the throughput as measured from 
publishing client to receiving client. (Adding in a reply queue and 
periodic status updates back from the consumer to the producer also 
allows such a test to 'throttle' itself and avoid the overload that 
Matthias refers to).
