dynaTrace AJAX Edition 3 makes building lightning fast Web 2.0 applications easy. Speed your page load times, optimize rendering, tune DOM execution, and compare to competition. Even integrate with Selenium, Watir or QTP. It's free, easy, and for both Firefox and IE. Speeding Page Loads-speeding page loads is a top goal of all web applications. AJAX Edition provides performance reports that analyze every visited page based on known best practices from Google, Yahoo! and dynaTrace. AJAX Edition performance reports list problematic JavaScript code that has performance impacts on page load time. Browser caching, network roundtrips and server-side request times are all variables it helps you manage for consistently fast page load times. Diagnose Firefox and IE-Firefox and IE often do different things with the same code. Now you can build with confidence in either and quickly optimize the other by comparing the two at the same deep browser diagnostic level. Save hours of tedious trial and error testing. Use the facts to speed results. Optimize Page Rendering-time to first impression is an important KPI. Know the time to first drawing event, how each element of you page is loading, and in what sequence and timing intervals. A Timeline View provides a visual recording of each rendering task. Compare IE to Firefox to more quickly optimize the performance of both. JavaScript/DOM Tracing-AJAX Edition traces both JavaScript execution as well as all DOM calls-perhaps the most performance critical component in the browser. dynaTrace uses patented PurePath technology for this unique deep tracing capability. Web Test Automation-AJAX Edition captures and records the activity generated by your testing tool of choice. Automate performance analysis across both IE and Firefox without modifying your test scripts. Compare to Peers-tune what matters most. Assure your code is faster and pinpoint what needs work with the deep details you need to fix and optimize fast.
