“The idea [in Crankshaft] is to heavily optimize code that is frequently executed and not waste time optimizing code that is not,” the two engineers said. “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. In the V8 tests, Chrome’s canary build was over twice as fast as Firefox 4 current beta and Opera Software’s Opera 11 preview. When pitted against Microsoft’s Internet Explorer 9 (IE9) beta, Chrome was more than five times faster.
