Summary:
I am using the SINEC driver and I wish to improve it's performance. What is one way of doing this?

Solution:
The Driver parameter "Polltime" for the SINEC driver defaults to 100 mS. This means that the driver will make a request every 100 mS. To improve this, set the parameter "Polltime" to smaller values. For example:

[SINEC]
polltime=50

Please note:

1. The acceptable values for the SINEC driver's polltime are values greater than 0.

2. Reducing the polltime will increase the IOServers CPU usage which may affect other Citect time critical functions. Care should be taken to avoid overloading the CPU.
