iPad 2 and iOS 4.3: Mobile Safari Performance Quadrupled

Early iPad 2 performance tests were released last week, and showed that a combination of hardware and software improvements made the iPad 2 one of the most powerful tablets around when it comes to JavaScript and web rendering.

The news initially came from CNET UK, who managed to run a quick JavaScript test on a demo iPad 2 after Steve Jobs’ keynote last Wednesday. The test showed that the iPad 2 was able to run JavaScript four times faster than its predecessor.

Earlier today, more tests were published, and show that while the new dual-core Apple A5 processor featured in the iPad 2 is indeed contributing to the performance boost, iOS 4.3′s new ‘Nitro’ JavaScript engine seems to be taking care of most of the heavy-lifting.

CNET JavaScript test - Smaller execution time is better

The iPad 2 is the clear winner of the CNET test, as the new device proved to be tremendously faster than both first generation iPad and iPhone 4, as well as Android devices such as the Galaxy Tab and the Google Nexus S.

While CNET did run some tests to compare the additional performance brought by iOS 4.3 alone, the folks over at iOSnoops ran a more comprehensive suite of tests on a first generation iPad, to check the tablet’s JavaScript performance before and after the move to iOS 4.3.

iOSnoops JavaScript test – Except SunSpider, higher is better

The additional tests show that on the exact same device, the new iOS 4.3 Nitro JavaScript engine can deliver up to three times more performance – an impressive result, to say the least.

Thanks to hardware and software improvements, the iPad 2 is poised to offer a dramatically improved web experience, especially on websites that heavily rely on JavaScript, such as Facebook, or most Google’s services, such as Google Docs. And if you do not plan to upgrade to the new tablet for now, and plan to keep using your first generation iPad instead, migrating your device to iOS 4.3 is highly recommended, as your ‘old’ iPad will render most ‘heavy’ web pages much faster once updated.

The BlackBerry PlayBook pwns the iPad 2.

The BlackBerry PlayBook pwns the iPad 2.

Any proof of that? because seriously it's looking the opposite, especially if they can't get the battery life up.

It's not looking the opposite at all. The units that the media had months ago didn't even have power management implemented, from what I'm told. I watched a cat test a bunch of tablets right in front of me and the PlayBook demolished them all.

They still don't. RIM won't say absolutely anything about the battery life except "it's the last thing they will optimize". They have a little more than a month to go before launch. That is not good.

The other drawback is software development hoops but at least there's still time to address that. Both RIM and Motorola are just worried about getting it out and fixing things later You can do that when you are dealing with people ok with new technology, but you can't do that dealing with the general public.

If you don't think so, you need some education on QNX, homey. By the way, how much RAM does the iPad 2 have? Why is Apple not talking about that? The PlayBook has 1GB and so do others.

Yes, it is. I used one today. Not sure what development hoops you're referring to.

One of the people on the tech side of my firm is a beta tester for the the playbook. That shit is not that hot homey. We got the original iPad from our job and honestly, I will stick with that. So far, it has proven to be more dynamic for the needs of a creative professional.

To each his own. I love it. For the record, I also have an iPad and a Tab, so I've tried all three. I've also developed for all of them.

Oh shit! I didn't know they were both on sale already. You da man playa....

So tell us what your experience has been on the 2 devices. What does 1 do better over the other, if any?

Funny. I suppose you don't have access to pre-release devices from multiple vendors, like I do. I forget what it's like outside of the aristocracy sometimes.

That's exactly what they are doing. I won't stand for that shit. Fuck both of them.

Not true, homie. Battery optimization is often one of the last pieces to fine tune. It was likely the same scenario with the iPad and the Tab...but they aren't under the same scrutiny, for some reason.
