I have a similar similar setup (flow control turned off) producer ==> EmbeddedConsumer ==> consumer. Producers producing messages to kaha persisted topics
In the test setup we have 10 producers per virtual-topic with 10 topics. There are 10 consumers for each virtual topic i.e., total of 100 producers, 100 consumers & 10 topics. *Issue 1: * When both producer and consumers are up and running we get a very good throughput from the setup. When consumers don't consume the messages the producer throughput *drops by 90%* *Issue 2:* We see ~750 threads in the system. 100 threads for producers, 100 threads for consumers is what we can account for. Not able understand why there are ~550 threads used by ActiveMQ. Even if we account 1 thread each for producer & consumer we account for 200 off of 550. Appreciate we can get a response explain this backlog issue and high resource usage. -- View this message in context: http://activemq.2283324.n4.nabble.com/Upstream-throttling-and-backlog-tp3451330p3767280.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
