Users can switch to Chrome canary, which is available only for Windows, by downloading that edition from Google's site.Ĭhrome's "canary" build was 40.5% than the "dev" edition in Google's own V8 JavaScript benchmark tests. There's more to real world performance than JavaScript." Last month, Dean Hachamovitch, a Microsoft executive who leads IE development, dismissed browser benchmarks as "at best, not very useful, and at worst, misleading. Of course, JavaScript benchmarks aren't the only measure of a browser's speed, a fact that Microsoft has repeatedly pointed out even as it's cited SunSpider results IE9. When pitted against Microsoft's Internet Explorer 9 (IE9) beta, Chrome was more than five times faster. 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. The more work an application does, the bigger the gains will be." "Because of this, benchmarks that finish in just a few milliseconds, such as SunSpider, will show little improvement with Crankshaft. "The idea is to heavily optimize code that is frequently executed and not waste time optimizing code that is not," the two engineers said. Google's Millikin and Schneider explained the small gains in SunSpider in their blog post Tuesday. SunSpider, created by the WebKit project - the open-source foundation of both Chrome and Apple's Safari - is the most widely-cited JavaScript benchmark. SunSpider scores showed that the canary edition was just 2.2% faster than the dev build and only 3.5% faster than the stable version of Chrome. In a third benchmark suite, however, the Crankshaft-equipped canary build proved only marginally faster than other versions of Google's browser. According to Kraken, Chrome canary was 55.3% faster at rendering JavaScript than the dev build, and 51.2% faster than the stable edition. Chrome canary also showed impressive speed improvements over earlier editions in Kraken, the JavaScript benchmark created by rival browser maker Mozilla.
