The early beta release of iPhone OS 3.0 offers Javascript performance improvements ranging from three to ten times faster than that of iPhone OS 2.2, according to numbers provided by AdMob employee Wayne Pan. Using iPhone developer Craig Hockenberry’s iPhone benchmarks page, Pan tested the new beta OS and saw large gains when running Javascript, suggesting the new build of MobileSafari is based on an advanced WebKit Javascript engine introduced last year. Originally dubbed SquirrelFish, it has since been renamed Nitro. The improved engine should provide faster performance when using Javascript-based web applications. [via DF]
