Hello Celebert, I am using apache-activemq-5.12.1.
I found out the issue. My subscribers were on same machine as ActiveMQ install. While 5 subscribers, consuming messages on same machine as install, it was quite intensive. I moved subscribers to a separate machine than install and it took 9 seconds to send messages and almost similar to receive. This is about persistent messages. For non persistent, in new setup, it takes 1.7 seconds which is acceptable. However, consumer (gets all msgs in 6 seconds) in is showing messages waiting for 1+ seconds. For SonicMQ, time taken is consistent irrespective of consumer on machine where sonic install is there. I feel that this 9 second is still high for sending 25000 msgs. It can do better. Also, can this CPU and memory intensiveness improved. I will go through Artemis. Sorry for naive query but how different Artemis is to ActiveMQ. I haven't explored that front.
