Ben Livshits and Emre Kiciman of Microsoft Research have released the Doloto performance-optimization tool. This cool tool enables web developers to optimize page-load time by ensuring that pages only pull in the JavaScript functions they need. Mentioned in Steve Souder's Even Faster Web Sites earlier this year, it's now available to the public.

Beyond the fact that I love tools that make the web faster, I'm particularly excited about Doloto because it's the first released project built on top of FiddlerCore.
