[rabbitmq-discuss] Query about performance

[Robert Raschke]

Hi Ashish,

from what you write, it makes me think that you just one queue, for both
the reporting and the demo. If that is correct, then try having two queues,
one just for the reporting and another just for the demo. If you then also
have two separate consumers, then the demo consumer will not be held up by
any reporting messages.

Regards,
Robby
