The US Open is one of the major world sport events these days. Those tennis enthusiasts that can’t make it to the Centre Court in Flushing Meadows are either watching the games on television or following the scores on the official US Open Web Site.

The question is: How long does it take to get the current standings? And – is my Firefox faster than my friends Internet Explorer?
Comparing US Open 2011 Page Load Time

I made this test easy. I recorded page load activity in both Firefox 6 and Internet Explorer 8 when loading http://www.usopen.org. I am using dynaTrace AJAX Premium to analyze and compare the activity side-by-side. The following screenshot shows the High-Level Key Performance Indicators for both browsers. The interesting observations for me are

  • Slower JavaScript Execution Time on IE
  • Slower Rendering in Firefox
