Windows 7 WebDAV Performance

This bugged me for a while...
DavDrive's WebDAV performance seems o.k. on almost all platforms, except for Windows 7 (and especially the 64 bit version).
I have no Windows 7 at home, so I could not really test.

Today I stumbled over a blog entry by Chief Oddball which suggests a fix.
To make it short, here is the possible fix (quoted form the blog entry):

1. In Internet Explorer, open the Tools menu, then click Internet Options.
2. Select the Connections tab.
3. Click the LAN Settings button.
4. Uncheck the “Automatically detect settings” box.
5. Click OK until you’re out of dialog hell.

I'm really interested if this is working.
Comments welcome!
