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.
