It must be caching the more popular torrents. Inception loaded up within 1s for me, which means there probably was no communication between the trackers and the server. Other torrents didn't even load up for me.
No ads. I live in a country with barely any ads targeted at it (only 1M people live here) - so I usually get none. It loaded up so incredibly fast that it must have been cached and stored on the server.
