During Apple's iPad 2 announcement yesterday Scott Forstall announced that Mobile Safari was getting a 2x performance boost, in part by porting over Mac OX's Nitro JavaScript engine.
As you surf the web, your fingers will love the responsiveness of the new Nitro JavaScript engine powering Safari. It runs JavaScript up to twice as fast as in iOS 4.2.2 Which means you get more speed behind each page load. And sites with lots of interactive features can appear on your screen even faster.
Users should see noticeable speed improvements under iOS 4.3 when visiting highly-interactive and complex websites across iOS devices, and when paired with the A5 chip and (presumably) more RAM on the iPad 2 it should really scream. Mac OS X Lion has recently been given a WebKit2 boost as well but there's no word yet on whether that will be carried over to iOS or when.
Are you looking forward to the Safari performance boosts coming in iOS 4.3? Let us know in the comments below!
