Hi Hudalla,
I spun up your configuration and got the same disappointing throughput
numbers. A network trace reveals that with the policy in place the
session handshake reduces the sender-to-router Incoming-Window to 1.
This means that only one message can be outstanding on the link until
the router returns a disposition that retires it. Then the sender is
free to send the next message. That causes the slowdown.
Adding the configuration lines:
"maxFrameSize": 16384,
"maxSessionWindow": 3276800,
sets the session so that it can have 200 messages outstanding. This
restores the performance to the 30,000 msgs/S region.
With no router policy in effect the Incoming-Window is 2147483647.
Essentially the sender can send an unlimited number of frames and
the session window will never be closed.
