  1. What is V8?
  2. What are we currently doing to speed up JavaScript performance on V8?
  3. How do we achieve big boosts in JavaScript speed, such as the recent 150% improvement since our initial launch?
  4. How do we measure V8′s performance?

    I think one of the most advertised strong point in Chrome is the script engine supposedly delivering far better performance than any other browser.

    This may be the case in the pages written specifically for Chrome but it is really not true on the everyday pages you can find on the Internet.

    On the contrary, Chrome may prove to be the slowest. I had noticed that when developing my site that uses the Image Flow js component from Finn Rudolph. Have a look at http://faltiska.net/en. Use your mouse scroll on the visual navigator.

    Do that in Firefox, Opera, IE and Chrome. Chrome is really bad. IE is annoying because of the tearing but the movement is more fluent. Firefox and Opera are near perfect.

    So, what is Google bragging about?
