Ok so to keep beating a dead horse but just wanted to update with a little more info. We just received new machines which are connected to a new, much faster network. Same thing is happening. The website loads fine, I always start by clicking "new posts" and go from there, works fine. Once I click on a thread, however, the website will load but the actual content of the thread, the posts, take forever to load. I tried this both logged in as myself and not logged in at all on both Chrome and IE. I did notice that the status bar at the bottom of the screen says "Waiting for connect.facebook.net...". I don't have facebook logged in on this computer so idk what that is about. I timed how long it takes to load, 7:30.04. I figured it was something on my end but I use a few different forums and this is the only one it happens on so this is why I am not sure if its my end or something on your end.
