Revamped WebKit JavaScript Engine Doubles In Speed

Shin-LaC writes "In a post on their official blog, WebKit developers introduced the 'next generation' of their JavaScript engine, SquirrelFish Extreme, claimed to be twice as fast as its predecessor. The post lists several changes contributing to the performance improvements, including 'bytecode optimization,' a 'polymorphic inline cache' (which sounds similar to V8's 'hidden class transitions'), and a 'context threaded JIT' compiler which generates native code (currently only for x86 processors), and is also applied to regular expressions. The new JavaScript engine is already available in the latest WebKit nightly builds. According to comparative benchmarks, the new engine is around 35% faster than the V8 engine recently introduced in Google Chrome, and 55% faster than Mozilla's TraceMonkey."

Well, enough of that, time for me to get onto more serious drinking.

You know what commitment is? The only bottle of red wine left in the house is one of those big 1.5 liter mothers. You know what? I fuckin' opened it anyway and I'm only about halfway through.

Re:Speed of JS engine matters why?

No real user understands this jive.

You have a lower ID than me - why do I have to explain that you are at the "news for nerds" site and not Fox News :)

I visited my parents today for a younger brother's birthday, and found a bottle of red they'd bought at 14.5% alc... I was so proud of 'em :-)
