Subject Re: Backlog data causes producers to slow down.
Date Tue, 13 Sep 2011 07:54:07 GMT
Hey Folks, 

I tried the concurrentStoreAndDispatchQueues="false" and it didn't help. I
still see around 10X drop in producer throughput with backlog.

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. 

Best
Bhupesh
