After about 30 minutes of checking posts my system gets real sluggish and has trouble navigating Discussions. The page is slow to scroll or allow focus for choosing a Post.
I suspect all the AD links. Here is an example of a netstat command.

Closing IE6 and starting again helps for about another 30 minutes.
This syymptom only occurs on TR and almost makes me want to say screw the site.
