However, despite a lot of repeated attempts, I'm not able to get more than 4-5k messages/sec out of any rabbit server. Here are the results of some tests:</div><div><br></div><div>Single connection, Single Exchange, Single queue: ~4000 msg/sec<div>Single connection, Single Exchange, Two queues : ~4000 msg/sec</div><div>Single connection, Two Exchanges, Single queue : ~4000 msg/sec</div><div><div><div>Single connections, Two Exchanges, Two queues : ~4000 msg/sec</div></div><div>Two connections, Two Exchanges, Two queues : ~3300 msg/sec (could be a fluke, haven't repeated this test)</div></div><div><br></div><div>The message rates I've NOT computationally verified - just reading off summary of what rabbit says is going through it's exchanges/queues. I'll probably work on some more accurate metrics later, but right now, I'm just trying to figure out what to tweak.</div><div><br></div></div><div>While the test was running, I saw at most a 2mb/sec data write rate, and only about 50-60% CPU use.
