Keynotes Ballroom ABCD
This is presentation will be streamed live along with the other keynotes.
Demos from HttpWatch, AOL Pagetest, Speed Tracer, and Fiddler.

AOL Pagetest

For more than two years, WebPagetest has been a leading tool for Web page performance measurement.

Now WebPagetest provides visual performance information via screen capture. You can correlate screen shots with waterfall diagrams to see what the screen looked liked at each moment of a page load. What’s more, you can perform side-by-side screen capture comparisons of two or more sites, and generate stand-alone video and filmstrip comparisons.

In addition, WebPagetest now provides CPU and memory utilization information during a page load, displayed, and synchronized with the waterfall diagram.

Speed Tracer

Speed Tracer is a tool to help you identify and fix performance problems in your web applications. It visualizes metrics that are taken from low level instrumentation points inside of the browser and analyzes them as your application runs.

I plan to give a quick overview of the Speed Tracer UI and then show off some of Speed Tracer’s new features. These include symbol de-obfuscation, full stack traces, server side traces, and integration with the Google Plugin for Eclipse.
