I suspect a large part of the difference between the measurements for 
the two systems may be attributable to the fact that publish is 
synchronous for durable messages in 0-10 (the next message is not sent 
until the broker acknowledges the previous one) whereas in 0-8 there is 
no confirmation of the publication (the fact that send() returns does 
not necessarily imply that the broker has even received it, let alone 
stored it).
