iOS 5.1 SunSpider benchmark

March 8, 2012

It’s been 24 hours since Apple released the iOS 5.1 update to several iDevices and I’ve ran on my iPad 2 the SunSpider javascript benchmark to check if there were any performance improvements.

As you can see in the screenshot above, there is absolutely no improvement… at all! The benchmark is completed in the same amount of time iOS 5.0 took.

The main noticeable improvement, at least for me in this first day of usage, is in the stability department: in iOS 5 and 5.0.1 it was common to watch Safari close by itself, especially when dealing with a large amount of tabs but with iOS 5.1 things appear to be much more robust.
