Since November 2011, when we last tested this set of 2,000 leading ecommerce sites, the median home page has taken a 9% performance hit, with load time increasing from 5.94 seconds to 6.5 seconds.
“Aren’t many of the performance rules described by Steve Souders in 2007 already outdated or made obsolete by browser innovation?” Here’s part two of my three-part series of posts answering this important question.

While each of these areas by itself may not amount to much, the cumulative performance penalty can be significant. And while you may not be able to make performance-improving changes to your (or your visitors’) security features, this makes a compelling argument for why you need to optimize all the other areas that are within your control.
We all tend to have semi-educated guesses about the browsers that people choose to use at work/school versus those they use at home, but there are few to no studies to validate them.
