A post earlier this week provided insight on several new IE8 features, see The Facts About IE8. In it we casually mention that IE8 RC1 makes great strides in performance that provide a faster day-to-day browsing experience.
If you are a bit curious about this claim we direct you to Microsoft’s recently released report titled "Measuring Browser Performance: Understanding Issues in Benchmarking and Performance Analysis” available publicly at the Microsoft Download Center. The results of the in-house benchmark study show that across the top 25 most popular web sites IE8 loads faster than Chrome 1.0 and Firefox 3.05 on 5 of the top 10 and 12 of the top 25.
The results are also publicized out on our IE8 site as a video case study and discussed further on Ars.
You be the judge.
