Analyzing Webpage Performance with AJAX Edition 4: 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 blog post I want to show you how to do it and what the typical differences in performance are.
