Android 2.2 cleans up with iOS4 in JavaScript Performance

iOS 4 vs Android 2.2

Ars Technica have released some statistics revealing the performance of Android 2.2 in comparison to the iOS 4 platform. Specifically, the performance benchmarks were based on JavaScript using SunSpider and V8.

To be honest, I am slightly surprised someone had not performed these tests already as they were screaming out to be run. First, it should be noted that the results show “JavaScript execution in Froyo’s Web browser is almost three times faster than in the previous version of the [Android] platform.” This is something we were expecting due to the high-performance JIT that was introduced in Android’s Dalvik runtime environment.

What is interesting is just how much better Android 2.2 performs at these JavaScript tests than the iOS. In the SunSpider tests, Android performs almost twice as quickly while in the V8 tests it receives a score four times greater than the iPhone 4.
