According to a Blaze study stemming from 45,000 Android and iOS tests, the Android browser on average loads web pages 52 percent faster than mobile Safari. The results are inconclusive, however, because it’s unclear whether Blaze’s measurements take into account the new Nitro JavaScript engine that comes with iOS 4.3. The report was completed before this complaint was made public and Blaze is arguing that the lack of Nitro boost can “slightly” skew the results given that “JavaScript only accounts for a small percentage of the total load time.”

The devices used for testing include a Nexus One running Android 2.3 and an iPhone 4 with, presumably, iOS 4.3. Both operating systems sport WebKit-based browsers.

On average, Android came in 52 percent faster with an average page load time of 2.144 second versus 3.254 seconds for the iPhone. Android apparently outperformed Apple’s handset on 84 of the tested websites, including those that are not optimized for mobile access. On mobile sites, however, Android’s lead dropped to just three percent.

Regarding that Nitro issue, a follow-up note on Blaze’s site says the following:

A spokesperson for Apple confirmed that “the embedded web viewer does not take advantage of Safari’s web performance optimizations.” Put simply, the new Nitro engine only kicks in the Safari app, not when viewing web pages in third-party apps that use the embedded web viewer. Meanwhile, the blogosphere exposed the Blaze survey as flawed because they actually tested the web controls of each platform using custom apps rather than actual browsers. Plus, Blaze technology chief Guy Podjarny admitted to operating under flawed assumptions:
