The WebKit guys have put together a new Javascript benchmark under the name “SunSpider“. It’s intended to go further than simple benchmarks like Celtic Kane’s and try to emulate real-world tasks. Safari/WebKit has been getting pretty quick on these benchmarks anyway, but this new one really shows its strengths. There are various comments about people’s results in the comments for that post, but no compilation for easy comparison, so I’ve put one together.
Updated: added Webkit Win and Opera 9.5b Win
Updated: Failed to run completely on Opera 9.5b Mac
Updated: Some stats for Opera 9.5b Mac and IE6
Updated March 18th: Added Safari 3.1, FF3b4, IE8
