Absolutely agree with respect to ads. While the steady state performance of most banner ads is fine, loading new ads often force large javascript files to be fetched and parsed as well as needless reflows. On our game building site [1], we try to refresh ads only during natural breaks in gameplay (level changes). While this doesn't improve the loading time, it does help to shift the disruption to a time when it is less likely to be noticed.

well, it's not surprising web apps are slow. as an example, 1dash1.com mentioned above: 57.480 lines of JS across 8 separate domains. and the result? site is loading slow (at least on my 500MBit/s fiber connection) and the browser is executing a lot of stuff, most of which is not really efficient or time sensitive (or required). this is how most sites does it, it has to be better ways.
