This is very unlikely to work. Message properties don't have very much 
to do with it.

In practice *by far* the biggest impact on latency is message rate - 
when the broker is near to its maximum message rate, latency heads for 
the sky. See the last chart at:

I would argue that RabbitMQ, like most software, is too complex a system 
to *model* with anything other than itself. If you want to find out how 
it will perform in a given context, take measurements.

Cheers, Simon
