WebKit Performance on iPhone OS X 2.0

John Gruber:

The results are obvious. WebKit JavaScript performance has improved steadily and significantly in just one year, with a huge jump between 1.1.4 and the new 2.0.0.

And yet his MacBook Pro (which may be running a less optimized version of Safari) is still 40 times faster. Macs are fast these days.

Update (2008-07-24) from John Gruber:

Recursion depth, in and of itself, isn’t particularly important. It’s just a particularly simple way to distinguish pre- and post-SquirrelFish versions of WebKit. And so since we now know that the iPhone isn’t yet using SquirrelFish, it means further dramatic performance improvements are on the horizon.
