To my understanding it is 10 seconds as refresh rate for real time reports. But this may vary depending on the network speed. Downloading of historical data takes precedence over the updating of real-time data. Therefore, real-time reports will update at a slower rate while historical data are downloading from the DEFINITY system to the historical database.
Also I would request you to refer to BCMRD User Guide.
Real-Time Graphs update as fast as every ten seconds. Downloading of historical data takes precedence over the updating of real-time data. Therefore, real-time reports will update at a slower rate while historical data are downloading from the DEFINITY system to the historical
database.
This refresh rate will also affect in scenarios where the BCMRD client and BCMRD server are installed on different machines (remote server/client scenario).
