Dean Hume - Measuring Web Page Performance with Selenium 2 and the Web

I have always been interested in measuring web performance, and especially in measuring the improvements in performance. A while ago I attended a Selenium Meetup in London and heard an interesting presentation by one of the QA guys working at Mozilla. He talked about measuring the performance of a web page over a period of time using Selenium 2 and logging these statistics so we can track client-side performance improvements.
