Faster apps for a faster web | News

Maybe you've crossed your mind, what's going on in the browser when a website or webpage does not respond quickly as desired visitors. Especially on a website that has many advanced applications.

But until now, it seems difficult for developers to identify problems in the slow-to-respond applications. So, tonight at the Google Campfire One, they will be happy to announce that they will add a new tool for Google Web Toolkit is called Speed Tracer.

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.

They think developers will find that Speed Tracer looks under the covers of web applications like never before. In fact, they even used Speed Tracer to optimize the performance of Speed Tracer itself! (It's really an HTML5 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.

This is one of many other improvements in GWT 2.0 — which they released at this evening's Campfire — that make building web applications fast, and the applications you build run even faster. Check out the Google Code Blog for more information and to watch our Campfire One developer announcement.
