It's great that Javascript is fast and all, but what about the HTML rendering engine? What about the network layer? What about the whole package? I remember a while ago that Safari had an SSL bug that failed to cache certain session data and therefore all SSL sites were dog slow, despite the rendering engine being fast. Is anyone doing any real-world benchmarking with actual websites? But since throwing in the Internet to the mix would throw off the results, perhaps a locally hosted web server to do the actual serving? Create a clone of several popular sites locally, serve them up to the browsers of choice, time the results, ???, profit!
