Do you ever wonder what's going on within the browser when a webpage doesn't load or react as quickly as it should? Many developers do, especially when trying to build influential web applications for their users.
But up until now, it's been complex for developers to identify problems in a slow-to-respond application. Google at Google Campfire One was happy to announce that they are adding a new tool to Google Web Toolkit called Speed Tracer.
Speed Tracer is a Google Chrome extension that allows developers to identify performance problems in their web apps using a "Sluggishness Graph," in combination with many other metrics. In the spirit of clean, easy 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 extra data to help identify any particular performance issue.
The developers will find that Speed Tracer looks under the covers of web applications like never before. In fact, Google 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.
This is one of many other improvements in GWT 2.0 which Google released in Campfire that makes 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.
