MSDN are testing a new version of the Library pages that are designed for low bandwidth connections.  If you browse to any library page you will see a link under the breadcrumb, e.g:

This will display a vastly stripped down version of the usual pages. 

You will be returned to normal mode if you navigate to any other library page or use the persist option at the top right of the page.

The speed of MSDN in this mode is great.  The only thing I miss is search.

Enjoy!
