Google introduce speed tracer

Google added  a new tool to Google Web Toolkit called Speed Tracer to identify problems in a slow-to-respond application.Speed Tracer is a Google Chrome extension that enables developers to identify performance problems in their web apps using a “Sluggishness Graph,” in combination with many other metrics. In the spirit of clean, simple design, 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

And in either case, Speed Tracer provides lots of additional data to help diagnose any particular performance issue.
