WebKit Nightly がさらに速く

Just three months ago, we announced SquirrelFish, a major revamp of our JavaScript engine featuring a high-performance bytecode interpreter. Today we’d like to announce the next generation of our JavaScript engine – SquirrelFish Extreme (or SFX for short). SquirrelFish Extreme uses more advanced techniques, including fast native code generation, to deliver even more JavaScript performance.

次期Safariに搭載されると思われる新JavaScriptエンジンがさらに速くなって登場しました。ベンチマーク(SunSpider)してみると、その差は歴然。Safari 3.1に比べてWebKitは3倍高速でした。

ベンチマーク:
Safari 3.1.2 (5525.20.1)…….Total: 3093.6ms (詳細結果)
WebKit Nightly r36640………Total: 929.6ms (詳細結果)

このごろのWebKit Nightlyは安定感が増してきて普通使用では問題ないくらいになってます。
