&gt; 10k&#x2F;s is no problem for RabbitMQ, even on aws t2 machines<p>Sending them from themselves to themselves you can do even better than that. Loopbacks aren&#x27;t useful metrics for message passing. <a href="http:&#x2F;&#x2F;bravenewgeek.com&#x2F;tag&#x2F;rabbitmq&#x2F;" rel="nofollow">http:&#x2F;&#x2F;bravenewgeek.com&#x2F;tag&#x2F;rabbitmq&#x2F;</a> is the most recent attempt to benchmark the various solutions (that I have found) and my own testing results in slightly less than the results shown...which I can only attest to unfamiliarity with RMQ, Kafka, etc. In the end, ease of maintenance only speaks to the weaknesses of solutions that need tweaking for specific topologies.
