I used to leave MR open most of the time. But lately, I've noticed that certain ads that appear on MR main pages seem to eat a lot of processor cycles. The biggest, though I don't think it's the only, culprit seems to be the banners from Crucial. When one of these is left open, I see Safari's processor use sit at about 20%. This has lead me to change some of my patterns, as this can be enough to cause hiccups in other processor intensive tasks. Is there any chance that some kind of guideline can be implemented with advertisers to keep them from using ad banners that chew up so many resources?
