Microsoft Research has released some exciting information about a new tool being worked on by Ben Livshits and Emre Kiciman. DOLOTO promises to greatly speed the loading of web applications. It does this by automatically making parts of the application load in the background or lazy load when they are needed. The results look extremely impressive. They tried it on a bunch of websites and saw around a fifty percent improvement in loading time on all of them. These included such content rich sites as Live.com, Live Maps and Google Spreadsheets.
