Abstract

Attend this webinar and learn from dynaTrace technology strategists who use AJAX Edition every day to combat typical challenges today’s AJAX developers and testers face:

Problems with isolating performance hotspots of your Web2.0 applications

• Network, JavaScript or rendering related issues
• Client or server-side issues

Fixing actual AJAX performance issues is more guesswork than actual science because its impossible to tell

• If the custom JavaScript code or the underlying AJAX Frameworks (jQuery, Prototype, etc) is causing the issue
• Whether excessive DOM access is slowing down your web sites
• How browser rendering times affect your web site performance
• The impact on asynchronous calls done via XMLHttpRequests, dynamic script tag insertions or other mechanisms

Cumbersome performance testing

• Cannot measure true end-user experience including rendering times
• Inability to test daily builds within continuous integration
• Profilers have too high overhead

No easy way to share results between peers

• Problems must be recreated (on different platforms) which often is very hard to do
