Please give a more detailed description of the refreshing issue you observe.
Did you measure latency and check if packages get lost in the network?
I didn't measure latency. When I tried to navigate or enter any values in the field, the screen is simply refreshing in white background and the response is very slow.
The cursor is keep on rotating in the white screen for few minutes and after some time it comes back to the original screen with the changes.
Below is the screenshot I am getting after entering any values in the field.
As Torsten suggested this is probably not a web direct issue but a network latency issue.
In case you have not seen this here is a good how to on optimize for WD
