Google Announces Chrome Extension to Diagnose Website Sluggishness

Google has announced a new tool to Google Web Toolkit called Speed Tracer. The tool identifies performance problems in web apps using a "Sluggishness Graph" in combination with many other metrics.
Developers need only look at the Y-Axis of their application's Sluggishness Graph to see how they're doing:
- If the y-axis is close to zero, then the app is fast
- If the y-axis registers around 100%, then the app is, well, sluggish
We think developers will find that Speed Tracer looks under the covers of web applications like never before. In fact, we even used Speed Tracer to optimize the performance of Speed Tracer itself! (It's really an HTML application after all, built with Google Web Toolkit, and deployed as a Google Chrome extension.) If you're a web developer, download and install Speed Tracer on the Google Chrome Developer Channel.
Take a look at the intro video below...
