ABOUT THIS SESSION:

Our 12pm (US ET) talk on Thursday Feb 11 will be "Trace Down JavaScript & AJAX Performance in your Web Application", with Andreas Grabner of DynaTrace (dynatrace.com). Note that this is a vendor talk about a free tool, and while not CF-specific, I thought it would be of interest to CFers.

This was originally scheduled for 12pm (US ET) talk on Thursday Jan 14 but the speaker lost connectivity just as we were about to start, so it's been postponed to Feb 11.

TOPIC DESCRIPTION: (provided by the speaker)

Wondering what is really going in your browser in respect to JavaScript execution, AJAX calls, DOM access and Browser Rendering time? What is really happening in those "blank spots" that you see in your network download breakdown chart? Who is accessing DOM how often and what is the performance impact? What is actually triggering browser rendering activity and how can it be improved?

Attendees will learn how to troubleshoot performance issues in modern web applications using the FREE dynaTrace AJAX Edition (http://ajax.dynatrace...) to answer the following questions:

• How much time is spent in JavaScript vs. AJAX vs. DOM access vs.
  Network Roundtrip vs. Rendering Time?
  
• Is it my JavaScript code or one of the JavaScript libraries that I am using (jQuery, GWT, DWR, Prototype, ...)?
  
• Where are my hotspots and what can I do to solve these problems?
  
• How can I automate problem analysis to pro actively prevent problems?
