Tim, We just ran another test with all 3 brokers, 2 producer hosts, and 4 consumer hosts ... and made sure that every broker had at least one consumer host directly connected ... and we saw the queues on broker1 build up immediately - event during the "ramp up" portion of the test. We're going to try the same test again - but with conduitSubscriptions="true" and decreasNetworkConsumerPriority="true" (both are currently false).
What should I look for in the logs to see if Flow Control is kicking in? I don't think it is because the producers keep on keeping on ... it's the queues on the brokers that are filling up - but nowhere near to the limit (we allow 100gb for persistent messages). Producers send persistent messages inside of transactions ... and consumers also use transactions. And we have useAsyncSend=true. System usage is configured as follows: <systemUsage> <memoryUsage> <memoryUsage percentOfJvmHeap="70" /> </memoryUsage> <storeUsage> <storeUsage limit="100 gb"/> </storeUsage> <tempUsage> <tempUsage limit="50 gb"/> </tempUsage> </systemUsage> ping statistics from broker1 to broker2: 16 packets transmitted, 16 received, 0% packet loss, time 15413ms rtt min/avg/max/mdev = 0.119/0.175/0.232/0.026 ms from broker1 to broker3: 16 packets transmitted, 16 received, 0% packet loss, time 15260ms rtt min/avg/max/mdev = 0.136/0.194/0.271/0.046 ms from broker2 to broker3: 15 packets transmitted, 15 received, 0% packet loss, time 14507ms rtt min/avg/max/mdev = 0.174/0.213/0.261/0.029 ms from broker1 to producer1: 15 packets transmitted, 15 received, 0% packet loss, time 14381ms rtt min/avg/max/mdev = 0.727/0.819/0.907/0.052 ms from broker1 to producer2: 15 packets transmitted, 15 received, 0% packet loss, time 14403ms rtt min/avg/max/mdev = 0.829/0.914/0.987/0.048 ms from broker1 to consumer1: 15 packets transmitted, 15 received, 0% packet loss, time 14354ms rtt min/avg/max/mdev = 0.758/0.882/0.963/0.051 ms from broker1 to consumer2: 15 packets transmitted, 15 received, 0% packet loss, time 14802ms rtt min/avg/max/mdev = 0.807/0.861/0.916/0.042 ms -- View this message in context: http://activemq.2283324.n4.nabble.com/Network-Connector-too-slow-when-receive-high-rate-persistent-message-tp4721293p4721448.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
