Are you doing anything about the computing footprint of ads themselves? I often end up blocking ads because of the sheer amount of Javascript bloat they load, which often slows down my light-weight laptops/phones. I would be less opposed to blocking them if they were a simple image and link.
Our javascript is super small in terms of loading the ad, and we don't allow advertisers to add their own JS. So it shouldn't effect performance at all.
