Google Crankshaft accelerates Chrome JavaScript

From the ‘Super-charged V8‘ files:

One of the big tech features of Google’s Chrome browser is the V8 JavaScript engine.

Now with a new overlay for V8 called. ‘Crankshaft’ Google is claiming a 50 percent performance boost for what was already a blazing fast engine.

“Crankshaft uses adaptive compilation to improve both start-up time and
peak performance,” Google explained in a blog post. “The idea is to heavily optimize code that is
frequently executed and not waste time optimizing code that is not.
Because of this, benchmarks that finish in just a few milliseconds, such
as SunSpider, will show little improvement with Crankshaft. The more
work an application does, the bigger the gains will be.”

That’s cool.
