The Minority Report

I don’t know what order to post the clips but I think I’ve decided to paste them in the order that I found them.

First we have Dan Grigsby on the Mobile Orchard:

Wayne Pan benchmarked JavaScript on the iPhone 3.0 beta as compared to the 2.2 release and found performance improvements of 3-10x for various calculations:
iPhone 3.0 JavaScript Performance: 3-10x Increase

Dan was quoting from Wayne Pan:

iPhone 3.0 definitely has something, (whether it’s SquirrelFish or Nitro), but it’s 3x-10x faster than iPhone 2.2.

Wayne Pan was nice enough to create a spreadsheet to calc all the crunchin’ goodness here.

Wayne Pan got the idea to crunchin’ his numbers because James Churchman used the WebKit detector from Ajaxian to possibly see that, yes, iPhone OS 3.0 could be using SquirrelFish.

James Churchman did a quick bit of detective work and pointed the iPhone 3.0 simulator on the WebKit detector that we blogged about in the past.
Ajaxian » iPhone 3.0 now with SquirrelFish Extreme?

James Churchman used the iPhone 3.0 simulator on the WebKit detector that John Grubber used orignally to test whether iPhone 2.x had the old mutant Squirrel.
<script type="text/javascript">
function recurse(n) {
if (n> 0) {
return recurse(n - 1);
}
return 0;
}
try {
// recurse(43687); // Highest that works for me in WebKit
// nightly builds as of 24 Jul 2008.
// recurse(2999); // Highest that works for me in Firefox 3.0.1
// recurse(499); // Highest that works for me in Safari 3.1.2
recurse(3000);
document.write("Could be SquirrelFish.");
} catch(e) {
document.write("Not SquirrelFish.");
}
</script>


It calls a simple recursive function 3000 times. Pre-SquirrelFish versions of WebKit fail with any number higher than 499. Firefox 3.0.1 works up to 2,999 recursions. A recent WebKit nightly, with SquirrelFish, worked for me up to 43,687, which is pretty deep. MobileSafari in iPhone OS 2.0 has the same limit as Safari 3.1.2: 499.

Jesus, that is really down the rabbit hole with the ol’ cut and paste but frankly, who the fuck wants to clickity, click all those freaking links? Not me…
