I ran a Pingdom test
, you can look for yourself. It's not FN's requests that are timed out as his site loads fairly quickly, it's the forum itself (forum.php) which takes up to thirty fucking seconds to load and that's for about 415k in information in total. Actually, the user is waiting for a response from the server, the info that's being requested is like 15k... Some other tests like the one Google Developers has, PageInsights, straight out crashed because of that time-out.

At a second glance Bes' argument sounds pretty logical but then again FedeNerazzurra takes like 2-3s to load... Maybe it's something about the request? I dunno. Disabling it temporarily for debugging will tell. This 30s wait time is a TTFB (Time to first bite) basically the server does absolutely nothing in that time. What about the league table, wonder where this info comes from?
