Re: high GC activity yields a high percentage of dead letter queue messages.

Agreed. We’re still bringing up some instrumentation using Grafana/KairosDB so my plan is to get some GC logs and analyze this over time and look at memory as it grows. If I can’t get that working in the next few months I might just use data dog as I know they have a decent JVM memory interface.

non persistent messages and maxPageSize queue performance

2014-12-31 Thread Alex Colomb
I've been tracking down some performance issues on one of our queues. The queue is hosted on an embedded broker. There is one producer and one consumer. All messages sent to the queue are non-persistent. The producer initially will have a burst of ~30k messages and then slow down to 100 messages
