Using dynatrace-ajax to track JavaScript performance _ javascript skills

DynaTrace has been committed to analyzing the performance of background applications for several years. Recently, they have entered the front-end performance analysis field by publishing dynaTraceAjaxEdition. it is a free BHO tool running in IE. although I like Firefox and all the plug-ins under it, I know that testing and debugging Based on IE is also very important. Once you download and install DAE (dynaTrace Ajax Edition), you must go to the program group in the Start menu and find dynaTrace. Obviously, the first thing to do is to enter a url link. Next, click the play icon and select "New Run Configuration" to enter a New URL.

One of the features of DAE is that it can run under a multi-page workflow. You can enter the starting URL and navigate to another webpage or start the Ajax feature, while DAE monitors everything in the background. When you close IE, you can analyze all the information collected by DAE.

The main feature of DAE that distinguishes it from other tools: in-depth analysis of JavaScript. The timeline is divided into different parts by detecting event triggers and JavaScript API calls. It contains an HTTP waterfall chart. Another feature is to save the DAE analysis results so that you can check and share it with colleagues afterwards. It also has some other interesting features, such as automatically formatting the simplified source code, so that you can view a more understandable version when debugging the streamlined code on site,You can also analyze the CPU usage and page rendering performance

When you need to analyze the performance problems caused by JavaScript, dynaTrace Ajax Edition contains the code details from advanced calls to actual execution,You can check which line of JavaScript code causes the page performance bottleneck.. I suggest you test this tool and add it to your performance testing toolkit.
