I was just reading some web performance audits by Paul Irish: https://docs.google.com/document/d/1K-mKOqiUiSjgZTEscBLjtjd6E67oiK8H2ztOiq5tigk/pub https://docs.google.com/document/d/1K-mKOqiUiSjgZTEscBLjtjd6... One of things he mentions on one of the sites, is Adsense looking at every scroll event, and doing tracking work which takes 25ms on a smartphone (his smartphone, likely to be high end). That means your scrolling performance is going to be inherently bad, probably below 30 fps one you take into account other work associated with the browser or the site. Having a browser which takes out this kind of code, but doesn't break the business model of the website owner does seem like an interesting idea. It seems like a major part of the mobile web is half-broken for these kind of reasons.
