The web performance enhancements included in Apple’s latest mobile operating system, iOS 4.3, are exclusively available to the mobile Safari web browser
“The embedded web viewer does not take advantage of Safari’s web performance optimizations,” Trudy Muller, a spokesperson for Apple, told The Register.
Apple’s statement comes as a response to controversy
started earlier this week when developers first recognized the notable performance gap between mobile Safari and the embedded web views in their own applications. The debate deepened yesterday when Blaze Software released the results of a study that implied Android loaded web pages 52% faster than the iPhone 4. Apple refuted Blaze’s results, citing the differences between Safari and the embedded web viewer.
Matt Asay, vice president of business development for Strobe, indicated that Apple filed the performance gap as a bug but marked it “not to be fixed by exec order.” On Twitter, Asay called the scenario
“slimy” and suggested it’s partly a tactic for convincing developers to focus on the development of native apps.
The real reasons for the performance gap may not be so sordid. Ars Technica observes
