##Abstract
You've heard it time an time again from Google and Yahoo - combining your external scripts to reduce the number of requests will improve the load-time of your website. Up until now, this has been common knowledge that people have accepted, because intuitively, it makes a lot of sense. But this advice was dished out in the early days of the web - before the look-ahead pre-parser/pre-loader (a feature of the browser that attempts to start downloading scripts as fast as possible by spawning a separate thread outside of the main rendering thread, whose only job is to locate resources and download them in parallel) had been added to browsers.
Today in modern browsers, leaving your JavaScript separated actually improves the performance of your site for a majority of different scenarios - even on mobile networks. In this talk, I will be discussing why this is, and showing some data collected around the world using RUM to prove this claim. As well, I will be discussing why leaving scripts separate will be even more important for the SPDY web.
