Alex Rudyy updated QPID-8085:
-----------------------------
    Description: 
The broker sending link endpoint sends flow performatives  when more than half 
of the credits issued by receiving link endpoint is used. Such behaviour is 
spec compliant, though, it might effect the messaging throughput as the 
unnecessary flows consume bandwidth and might impact the performance.

We can simply restrict the sending link endpoint to send flow only in reply to 
incoming flows with echo= true or drain=true.
