I've talked to a few friends and this seems to happen to them as well. When I visit DiabloFans (chrome, IE, mobile, etc.) the page is responsive for a couple seconds and then freezes for as much as 10-15 secs before becoming responsive again. I've noticed, when the page loads, the blue tracker/recent posts lists the Thread Title with the author and creation date/time under it. This date/time is in the format mm/dd/yyyy hh:mm:ss am/pm. The page unfreezes when this date/time switches to "x hours ago". I believe there is something wrong with the script that converts the post time. It is not an issue on MMO-Champ (when the site initially loads it already shows in format "x hours ago". The issue is also present on Hearthpwn and HeroesNexus.
