First RTU port and TCP are polled together. Devices are polled in a queue one by one. You can potentially speed things up by using the second RTU port.
Persistent mode does not affect the polling speed. It's needed for devices that can handle only a limited number of TCP connections.
General performance recommendations:
- increase poll interval
- remove unnecessary data points
- use block reading where possible (read_count and read_offset profile fields), this can significantly reduce the polling time for each device
