Faulty Javascript benchmarking sparks AndroidiOS flame war

first_imgYesterday, website analysis firm Blaze seemed like they had put quite the feather in the cap of the Android crowd: they reported that the Nexus S smartphone running Android 2.3 loaded websites as much as 52% faster than an iPhone running iOS 4.3That’s a pretty staggering performance gap between Android and iOS 4.3, especially considering the fact that iOS 4.3 contains some much heralded improvements to iOS’s JavaScript engine which Apple has loudly and proudly boasted would vastly improve website times on Javascript heavy sites like Facebook and Twitter. AdChoices广告It didn’t appear to be a fluke, either: Blaze tested over 45,000 websites before they came to their conclusion. The study measured load time on the sites of a thousand Fortune 1000 companies over WiFi, and found that the Nexus S running Android 2.3 loaded the sites faster 84 percent of the time. The median load time for the iPhone 4 on iOS 4.3 was 3.25 seconds, while the Nexus S’s median load time was 2.14 seconds. The gap between mobile sites was less, but still came out in Nexus S’s favor.Don’t congratulate yourself on going the Android route quite yet, though. It turns out that Blaze didn’t use Safari for its tests, just its own iOS app and the system browser available to apps under iOS. According to Apple, that universal browser that any app can use doesn’t have access to the same Nitro improvements as the latest version of Safari.“Their testing is flawed because they didn’t actually test the Safari web browser on the iPhone. Instead they only tested their own proprietary app which uses an embedded web viewer that doesn’t take advantage of Safari’s web performance optimizations,” Apple spokesperson Trudy Muller told Ars Technica. “Despite this fundamental testing flaw, they still only found an average of a second difference in loading web pages.”Where this leaves iOS 4.3 is unknown, but it seems pretty clear that Blaze’s initial data is way off. For now, though, it appears the true victor of the Android/iOS Javascript benchmarks is up in the air.Read more at Ars Technicalast_img
