JIT Performance Benchmark Android 2.2 vs Android 2.1
When Google announced Android 2.2 (Froyo) last week, they said that it comes with a new JIT (Just-In-Time) compiler, that will bring you enormous speed increases. In the video you’ll see how Android 2.1 runs compared to the new Android 2.2.
In the video, the Nexus One is in charge of Android 2.2, and Motorola Droid and Sprint Evo 4G again of the Android 2.1 (Eclair) side. Please note that the Nexus One’s Android 2.2 isn’t the final version, but a pre-release version that hasn’t been fully optimized.
