Hi all, The default refresh rate is 1 second. Would performance degrade significantly if I change the refresh rate to 0.5 seconds or less. For our system, the real-time aspect is quite critical. I plan to run experiments, but I thought it might be a good idea to hear if people have tried similar things? Cheers, Vijay ---

Refresh rate creates more load on the system as it happens, and, depending on your update rate. But I think you should be ok.
