1 Queue , 8 producers, 2 consumers , No backlog : 1200 QPS (producer), 1200 QPS (consumer) 1 Queue, 8 Producer, 2 consumer, 4GB backlog (2M events): 120 QPS (producer), 1200 QPS (consumer) I am attaching the scripts I am using, unfortunately I am using stomp and a perl based consumer/producer setup.
