Windows 7: MS JSMeter: A new way to analyze and affect JavaScript

The Microsoft Internet Explorer (IE) team isn’t the only group at the company that is delving into the finer points around JavaScript. A couple of Microsoft researchers also are doing work that could change the way Microsoft (and possibly other companies) look at — and ultimately affect — JavaScript runtime performance.

JSMeter isn’t a brand-new project, but I just learned of it via a new Microsoft Channel 9 video on the topic. Ben Livshits and Ben Zorn, two of the Microsoft researchers behind the project, made some interesting points during the part of the interview I watched. They explained how they took an implementation of Internet Explorer and changed the source code to see how they could affect the performance of Web applications, like Bing Maps, FaceBook and Gmail.
