Note:
Please note that a technical limitation of
the driver connections cannot necessarily be achieved by a single driver. Depending on
the load and dimensioning of the system, number of data transfers, etc., we recommend splitting the driver connections across several driver instances or distributed systems in order to reduce the individual load on a driver.
