dynaTrace AJAX Edition Surpasses 10,000 Downloads

Free Tool Analyzing Web Site Performance for Internet Explorer Reaches Milestone Among Developers

BOSTON, MA and LINZ, AUSTRIA--(Marketwire - March 30, 2010) -   dynaTrace, the innovator and emerging leader in application performance management (APM), announced today that its recently released AJAX Edition tool has exceeded 10,000 downloads. The free tool allows developers and IT managers to diagnose and troubleshoot AJAX performance problems found in common Web 2.0 applications.

Writing in his blog after the dynaTrace AJAX Edition launch last November, jQuery creator John Resig wrote: "I'm very impressed with dynaTrace AJAX Edition's ability to get at the underlying 'magic' that happens inside a browser: page rendering, DOM method execution, browser events and page layout calculation. Much of this information is completely hidden from developers and I've never seen it so easily collected into a single tool. Huge kudos to dynaTrace for revealing this information and especially so for making it happen in Internet Explorer."

As companies are delivering richer Internet applications in the browser, these new client-side application extensions deliver more interactive applications, but also unique problems. dynaTrace AJAX Edition brings the company's server-side APM technology to this growing set of performance challenges. It provides deep visibility into how AJAX-based applications work in the browser and code-level insight into frameworks such as jQuery, giving developers a powerful way to optimize the performance of their AJAX-based applications.

E-commerce leader used the AJAX Edition to quickly optimize their front-end performance and got an almost 10x improvement in speed: "We've been able to see from the load time how much of the impact is JavaScript, what actual functions are causing the slowdown, to the DOM interactions to see how that's impacting performance," said Morgan. One area that Morgan found particularly slow was the rendering of their home page drop-down menus. "Using dynaTrace we were able to find out that it was primarily determining the position of the drop downs that was causing the slow down," Morgan said. "So we saw almost a 10-fold increase, just by doing that one little thing alone." View the full video case here (

"When we created the AJAX Edition, our goal was to develop a robust, free tool enabling developers to understand application performance as real users experience it," said Andreas Grabner at dynaTrace. "We had no idea demand for this dynaTrace AJAX Edition would grow to this level. We're extremely pleased by the feedback from the growing community and look forward to bringing additional functionality to the product, such as Firefox support."
