Some site themes result in insanely high cpu usage. Try Animal Crossing or Milk and refresh the settings page. I think it is related to moving background objects.

Cause seems to be located in

jQuery(document).on("srcom:ready", function() { ... })

Calling a $("body") or $("#foreground") selector 100 times a second is insane. 25% cpu usage on a good i7 is pretty serious.

nice page, the very way bootstrap should be used.

I am however missing a search function for the forum :C would be helpful
