Firefox’s JavaScript engine, Spidermonkey (including the Tracemonkey and Jaegermonkey JITs) is now faster than Webkit’s JSCore on both Sunspider and V8. Great work, team!
Also, on the Sunspider benchmark, Mozilla is only about 1/100th of a second behind Chrome’s V8 JavaScript engine (about 3.5%). Oh, and there’s Kraken, where we’re still solidly in the lead.
