Folks at iSpazio have carried out some tests to find out the real world performance improvements of Safari browser in iOS 4.3 GM compared to iOS 4.2.1.
You can checkout the video to checkout the results:
Gizmodo also carried out a similar test, unfortunately their video has been pulled as it probably violates iOS developer agreement to publish videos of iOS 4.3 GM but they observed that ‘iOS 4.3 GM was just a few seconds faster than iOS 4.2 loading the NY Times in Safari’.
As you can see, it’s not a major improvement in speed but it is definitely faster. Let us know your thoughts in the comments below.
