Microsoft’s own speed tests show IE beating Chrome, Firefox (Updated)

Just before announcing that Internet Explorer 8 has been finalized, Microsoft has released a new report titled "Measuring Browser Performance: Understanding issues in benchmarking and performance analysis." The document explains the various browser and network components and how each piece can impact performance when benchmarking, capabilities and limitations of various benchmarking tools, as well as ways to design tests to avoid these issues. What makes this report extremely dubious is the chart that is buried at the bottom. It shows IE8 outperforming Firefox 3.05 and Chrome 1.0, something that no other test on the Internet has ever shown before.

 

the table Microsoft provides shows the load times for the top 25 websites according to comScore, and IE8 does quite well. The report notes that Microsoft "used the browser ‘Done’ indicator for timing when the page when the page is completely loaded at that point. For pages which continue to load and change after the ‘one’ indication we have used common visual cues to generate the timings. Timing is started when the Go button is pressed. These timings were captured in January 2009; because Internet content is always changing you may get different timings when you run these tests."

As you can see, IE8 outperforms Firefox 3.05 and Chrome 1.0 in loading 12 websites, Chrome 1.0 places second by loading nine sites first, and Firefox brings up the rear by loading four sites faster than the other two browsers. Also, in case you missed it, IE loads mozilla.com faster than Firefox, and Firefox loads microsoft.com faster than IE, just for kicks. This report is bound to stir up a lot of controversy, especially since Microsoft outlines its exact methodology. The report is available publicly at the Microsoft Download Center in PDF and XPS formats, so check it out if you have the time for reading through 14 page
