hi,
I am working on Message broker v6.0 on Sun Solaris operating system.I have deployed pub sub message flow on the server.
We are using Publisher java program to publish the message on the queue (which is queue of the MQ Input node) and Publisher node publishes this message to the queue which has subscribed for the topic. So the flow deployed has only two nodes 1) MQ Input and 2) Publisher Node.Publisher message size is 2kb .we are publishing over a single topic and only one subscription for that.

My Problem is, I see same throughput(around 90 msg/sec) even if i increase the Message Flow instances of pub sub flow from 0 to 16 (where i expect increase in througput with increase in the flow threads,at least till saturation point is reached)

Is it regular behaviour of broker or I am missing some thing
