What can this new toy do?~3000 messages per second to a topic (which is more work than a queue)We have gotten 20,000/s to a single queue with 4 MusLatency should be a constant rate – no more long tails
Recap: When to use Premium Messaging
When you have massive scaleWhen you are latency sensitiveWhen you get lots of Server Busy errorsWhen you care enough to send the best
When not to use Premium Messaging
When you’re cost sensitiveWhen you’re not in a hurryAny time not listed on the previous slide
