Wasn't activated for me  which is the setting i prefer by default. Btw i'm a bit confused by the choice in this software. The software used by anandtech and hardforum seem much cleaner (page layout) and much faster.

Also why are you running windows ?

The forum is running on Ubuntu. The main site is running on Windows Server.

About the speed - the forum seems plenty fast to me and I'm living in the industrialized country with the lowest internet speeds ... (and the server is in Germany).
I'm somewhat puzzled myself why the main portal is so slow. The windows server is mightily strong and sees barely any load. 
Both sites are delivered via a CDN (Cloudflare).

Why windows on the main site? Well, while I can handle Linux the usability is generally ... crap.
IIS is much easier to configure than Apache HTTP where how-to-configs are communicated as if they reside in the land of myths and legends and the only way to access them is by defeating an army of orcs. Some people enjoy such text adventures, I don't.
