Banner machines eat a lot of CPU

The more tabs are open (I have Maxthon), the more percent is loaded and even scrolling (Pentium 4, 3.0GHz) slows down on all tabs. As soon as I close the Habr - everything flies, with the flush disconnected - also ok. I would not be surprised if, since the installation of this banner, attendance statistics for IE has fallen.

PS just do not need to let go for IE, I can typeset everything, but I like browsing in Maxthon.

Upd. They say it slows down in all browsers.
