That's not much! I have about 800 msg/sec (1KB size each) on a normal

No.
It seems that you don't receive the messages for the durable subscriber
but the messages which are *currently* published on that topic. Have you
set your client id correctly at your durable subscriber and do you use
the same id (and durable name) on each connect? Do you receive messages
when there is no publisher active?
May be there is some other delay within your subscriber client (within
the loop)?
That's all what I can tell you. As mentioned above, I have a rate of
800/sec also with receive(1000).
