Android versus iPhone OS 4: Which is faster?
Ars Technica reports that Google’s Android mobile operating system got some significant performance improvements in version 2.2, codenamed Froyo. A high-performance JIT was introduced in Android’s Dalvik runtime environment and the browser received some very deep optimizations.
To determine the extent of the performance improvements, Ars Technica ran SunSpider and V8 benchmarks which tests the JavaScript execution in the device’s default browser.
The results showed that the Nexus One running Froyo was able to execute JavaScript significantly faster than the iPhone 4 running iOS4. Ars states that this would translate to an improved experience on script-heavy websites.
Benchmarking the Nexus One against itself but running the previous incarnation of the Android operating system, Eclair (or 2.1), showed that Android 2.1 on a Nexus One was just over 3 seconds slower than iOS4 on an iPhone 4.
Engadget opted for a less academic approach and tested the two phones side-by-side on more everyday websites.
The result is still a win for Android, but by a much smaller margin.
With Flash 10.1 enabled on the Google Nexus One (a feature not available to iPhone), the iPhone consistently loaded the Engadget site faster whereas the Nexus One loaded the New York Times faster.
Disabling Flash resulted in the Nexus One loading four out of the five sites tested (Engadget, New York Times, gdgt and The Onion) faster.
