the performance of the page.
You can access this with javascript via the object window.webkitPerformance
More info on the Chromium blog
<http://blog.chromium.org/2010/07/do-you-know-how-slow-your-web-page-is.html>
and the Technical Spec <http://dev.w3.org/2006/webapi/WebTiming/>.
They also mention that a similar object is available in the IE9 preview
window.msPerformance and that Mozilla are also working on one.
Maybe we could have a unified object in the future with a standard
implementation?
