Web application performance company New Relic released the results of a study comparing the mobile browsing speeds of iOS 4 and iOS 5 on the same model of iPhone. What did they find? That iOS 5 / Safari 5.1 is much faster than iOS 4 / Safari 5.0.
New Relic complied their test results into the nifty infographic seen below. I love their conclusion: "Time to upgrade!" What has been your personal experience with web browsing or web app response times under iOS 5 and Safari 5.1? Leave your comments below.
