>>All webOS apps are based on javascript, so a fast js implementation is crucial for the palm pre.

That’s true that you want a fast JS, but my bottleneck on Mobile Safari games has been touching the DOM. JS goes along at a great clip then–boom–I touch the DOM and everything stops. That’s my experience anyway.

I have found out that the webkit used in webos uses the V8 JS engine instead of the SquirrelFish Extreme/Nitro engine. Probably the pre performs much better in the V8 benchmark (or realworld js).

@AndiSkater > Well, it’s not just about hardware. The new iPhone 3GS also benefits from the latest optimization that were achieve in the WebKit engine.
As the Pre is also based on the WebKit engine, an update of it’s OS could probably ends up with the same speed than the 3GS.

@digitarald: SunSpider is a publicly available test. Do it yourself.

I’d be interested in G2 numbers (I have mine since 2 months … US market is so slow ;)

The performance of the Palm Pre is a bit disappointing, as is has the same processor as the iPhone 3GS and shouldn’t be so much slower. All webOS apps are based on javascript, so a fast js implementation is crucial for the palm pre.

I wish someone could run all the common js/html tests on these devices.

I’m eager to try DOM manipulation. That’s what seemed slow to me on iPhone OS 2.2.1. And it’s why the css animations and transitions have been so important.
