@jkarneges just to give you a quick update, I ran everything (pushpin, my backend and loadtest) on an ec2 instance. Seems to be doing a lot better than my macbook pro. However, when it got to our beefy load test, it still struggled albeit a bit better than my macbook pro. When I set message_rate to 0 in pushpin.conf, the message loss rate basically halved. And now I'm trying to replicate this on kubernetes.
