iPad2 isn't as fast as you imagined?! Web browsing Benchmarks for iPad2 released

CNETUK ran the SunSpider JavaScript test on both the iPad1 and iPad2. Even though the iPad2 has a dual-core processor, its JavaScript speed test was only 1.5 times faster than the iPad1. Additionally, CNETUK found that the iPad running iOS 4.3 was faster than when running iOS 4.2, indicating that iPad users can upgrade to iOS 4.3 for better performance.

Of course, this test result focuses mainly on web browsing. The CPU of the iPad2 is indeed more powerful than that of the iPad1. Detailed results will only be known after Apple starts shipping the iPad2.
