Based on pure Javascript tests conducted by ArsTechnica to compare the recently released Android 2.2 and iOS4, results show some great performance by the Android browser. The credit goes to the new JIT engine in Froyo which has heavily optimized the browser.
The test were conducted on Android 2.2 running on Nexus one and Apple's Safari running on iPhone4, powered by iOS4. Two benchmarks were used to compare the results - Sunspider, where Javascript execution on Android proved to be twice as fast as iPhone4 and V8 where Android was three times faster.
As we can see, Google has done some sensational job with Android 2.2. Chrome has always been a good peformer at browser benchmarks and Google has maintained its reputation with the mobile browser too.
