I’m a little late to the party (dynaTrace released their product a couple weeks ago), but I wanted to still highlight their very important tool: dynaTrace AJAX Edition. It’s by far the best browser profiling tool out there – and it’s free!
If you’re familiar with Firebug, then that’ll give you a rough idea of what this product does. However, instead of being a “Swiss Army knife” like Firebug is, dynaTrace did a deep dive on JavaScript profiling.
This means that this tool can help identify hotspots and bottlenecks in your client-side JavaScript. And as applications continue to get more complex, this will continue to be a bigger and bigger area that developers need to keep an eye on. Ultimately, it doesn’t matter if your server is fast if the client application is getting bogged down due to inefficient JavaScript and DOM calls.
Rather than launching in to a full overview of what dynaTrace AJAX Edition does, I recommend the following three articles:
- A Step-by-Step Guide to dynaTrace Ajax Edition – by Andreas Grabner, technology strategist @ dynaTrace
- dynaTrace Ajax Edition: tracing JS performance – by Steve Souders, chief performance engineer @ Google
- Deep Tracing of Internet Explorer – by John Resig, creator of jQuery
If you’re working on performance optimizations for your site, especially if you are concerned about IE (and let’s be honest, who isn’t?), do yourself a favor and add this tool to your toolset. You won’t be disappointed.
Note: I should add that BrowserMob is a dynaTrace partner and we are continuing to explore ways in which BrowserMob, Selenium, and dynaTrace products can work in concert.
