Configure Peer-to-Peer Communication Chapter 17
Reconfigure ResponseTime
The ResponseTime initially configured in Define Peer-to-peer
Parameters on page 186 was derived from theoretical considerations
and was chosen conservatively, to start the network running. The
ResponseTime actually needed is usually much smaller than the
theoretical value and can be optimized to improve network
performance.
To optimize the ResponseTime, follow these steps.
1. Open the Control Panels for all controllers in the project and
choose P2P State.
2. Position the horizontal slider so that you can read the
ResponseTime.
3. Compare the RspT avg of two linked controllers for the forward
and return path.
Values for RspT avg may jump a bit.
4. Watch both readings for a couple of seconds and pick the
largest value.
Your reading need not be accurate to the millisecond.
