Merely mapping googleads.g.doubleclick.net to 127.0.0.1 made a huge difference to my browsing experience. Despite the resources of Google, that server is waay overloaded. I was staring at the browser status line waiting for that server to cough up, so the page could render correctly (or at all). Supposedly, there are ways to embed doubleclick ads that do not slow down page rendering. However, most of the sites I visit haven't mastered the technique.
