It's been a while since we released the last major version of Compuware dynaTrace AJAX Edition. With AJAX Edition 4 we introduce the capability to test across all versions of Internet Explorer (IE) starting with IE6 and all versions of Firefox starting with 3.6.
Why is this important? Well, check out the test results of several pages we tested on IE6, 7 and 8 and contrast them with tests of the same pages using Firefox 16 and 18. A product page on Zappos.com loads in 1.3 seconds in Firefox 18 as compared to 5.6 seconds in IE6. That is four times slower on IE's rather ancient browser. Despite a concerted effort by the industry to get people to use updated browsers (including this one by Microsoft), we're still seeing a big mix in the browser versions people use to access websites. That means it's important to analyze webpage performance across browser versions to ensure your site functions and performs as it's supposed to.
In this article I want to show you how to do it and what the typical differences in performance are.
Step 1: Download Free Compuware dynaTrace AJAX Edition
Go to the AJAX Edition webpage and click on the download link. Run the Windows installer and launch it from your Start menu. You will be prompted to register a new APM Community account; use your existing account or continue with a five-day registration-free period. After five days the product remains free to use but you need to register an account. Registering a community account gives you full access to the discussion forum on the Compuware APM Community Portal where you can network with AJAX Edition peers and Compuware application performance experts to learn best practices, post questions and find troubleshooting tips.
Step 2: Capture Data Across Multiple Browsers
Now we are ready to start capturing performance data.
Click on "Click here to start tracing" and select either IE or Firefox. As you will be testing a web page you will be prompted for a name and a URL that you assign to that name, e.g., Zappos and zappos.com. Click "Run" and AJAX Edition will launch your browser and navigate right to that URL.
The AJAX Edition toolbar in IE and Firefox (here it's a status bar) indicates that the browser is connected to AJAX Edition and capturing all performance-relevant data while the browser is connected.
You may need to modify your browser's settings for this step to work properly. Check out our tips page for more information.
Step 3: Analyze High-level KPIs
I recorded several steps on zappos.com with different browsers. I used IE6, 7, 8 and Firefox 16 and 18. As I don't have all these browsers installed on my local machine I used different machines with AJAX Edition installed locally. After recording my sessions I exported the data into a dtas file and imported it all into my local AJAX Edition instance for analysis. This is also a typical use case in test departments where tests are done on different machines with different configurations. A performance expert receives these sessions for analysis and comparison.
All sessions are now available for analysis. Double-clicking a session opens the Performance Report showing high-level KPIs for each URL visited.
If you want to know the details about how these KPIs are calculated you can read up on them on our Best Practices on Web Performance Optimization community page.
Check out the following table that shows the key metrics across the different browsers for one of the product pages. The Fully Loaded time is the important metric to look for and the Client Time (Java Script Time) is the one metric with the biggest contribution to that Fully Loaded time:
When looking at the Timeline View of the fastest (IE8) and the slowest (IE6) browsers, it is easy to spot where the differences are during page load:
Step 4: Deep-dive Analysis
If you want to learn more about the deep-five diagnostics options I recommend, check out the online video tutorials on the specific views: AJAX Edition Tutorials.
Step 5: Compare Against Your Competition
Optimizing your site to work well on different browsers is great, but what if you are still much slower than your competition? AJAX Edition has built-in integration with Speed of the Web, which allows you to compare your KPIs against other websites in your industry. Once you have registered a community account and activated your copy of AJAX Edition you can select a category on the first tab in the Performance Report. Your KPIs will then be compared against the latest tests done by Speed of the Web.
On Speed of the Web you can select a category and see how your web performance optimization efforts compare to your competition.
Speed of the Web not only provides the KPIs of the top sites in different industries, it also allows you to test your own site using the same testing infrastructure as used to compute these values used in the comparison. Go to the SpeedoftheWeb.org and enter your URL. Not only will you get an online result of a tested URL you've entered, you will also get an AJAX Edition Session for download as Speed of the Web uses AJAX Edition to run these tests.
Step 6: Go Beyond Your Browser
There will be 20 billion IoT devices connected to the Internet soon. What if we could control these devices with our voice, mind, or gestures? What if we could teach these devices how to talk to each other? What if these devices could learn how to interact with us (and each other) to make our lives better? What if Jarvis was real? How can I gain these super powers? In his session at 17th Cloud Expo, Chris Matthieu, co-founder and CTO of Octoblu, will show you!

Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/target - this makes the integration of these separate pipelines and the coordination of software upd...

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...

The IoT market is on track to hit $7.1 trillion in 2020. The reality is that only a handful of companies are ready for this massive demand. There are a lot of barriers, paint points, traps, and hidden roadblocks. How can we deal with these issues and challenges? The paradigm has changed. Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
