View Full Version : Safari performance in iOS 6

Jun 12, 2012, 07:32 PM
Hey guys,

It seems that Apple worked on Safari's performances in iOS 6. Running a Sunspider JavaScript benchmark on my iPhone 4S in iOS 5.1.1 was giving me 22XXms and now it's around 18XXms. Kinda cool. I haven't tried my New iPad yet but results should be better too.

I just wanted to share this with you guys.

1631ms. +/- 1.6% 1st run.
1465ms +/- 0.4% 2nd run.
New iPad.

Needs work then. My galaxy nexus on chrome gets 1349ms.

This is just a Minor update, but the loading bar is much smoother if u look at it. I like it:))

On iPhone 4, Browsermark has improved from the iOS 5 51,xxx to 60,xxx on iOS6: about 18%.

Sunspider has improved from 35xx on iOS 5 to 29xx on iOS 6. Also about 20%.

Not bad for a two year old phone! :D

iPhone 4S results:
Browsermark iOS 5: 88xxx
Browsermark iOS 6: 107xxx

Sunspider iOS 5: 22xx
Sunspider iOS 6: 17xx

Again right under 20% improvement.

To compare to Android the HTC One S sunspider clocks in at 1900 on the dual core 1.5ghz Krait using Chrome. According to anandtech the international quad core Tegra One X gets about 1750, the AT&T One X gives 1600 and the international quad core Exynos Galaxy S3(the one the US isn't getting) gets about 1450.


All in all, very impressive turnout from Apple from an OS upgrade.

Finally at home. With a freshly rebooted iPad 3rd gen I was able to get a browsermark of ~130,000 and a sunspider of ~1500. Big improvements over the launch benchmarks of ~100,000 on browsermark and ~1800 on sunspider.

I noticed right away that safari seemed quicker when loading pages!
