John Resig has put out Dromaeo maybe a touch before he wanted to due to people finding it :) The site hosts a subset of the WebKit Sun Spider JavaScript engine tests right now, with the desire to push on and do a lot more.

You can run tests and then compare your own results. What is particularly cool about all of this, is how we can harvest performance data. If enough people start running this bad boy from different parts of the world, and different devices (especially mobile devices) we will get a nice picture of performance of JavaScript engines.

The Mozilla Wiki has more information which covers the methodology, changes the other browsers would like to see, how to download and run locally, and a lot more.

Cool stuff. I hope to see this expand beyond JavaScript too and get even more “real world”.
