I found after using the “google-o-matic” several possible solutions.
The right way to go? well check this out, the delay is caused by IE. Yes that’s right it has nothing to do with SharePoint.
So what to do.See the figure below:
Open IE and check the connections tab.
Choose LAN settings and check use proxy and check Bypass proxy and choose Advanced.
Put your localhost ip 127.0.0.1 and port number 80 in the boxes.
And check use the same proxy and don’t forget to fill in exceptions ” *.* “
This can also be done by a group policy. Just start the GP editor
