Steve Souders, the web performance evangelist at Google, taught a course last year at Stanford’s Computer Science Department based on his highly regarded ‘High Performance Web Sites’ book. The course materials including slides, notes and labs are available from Steve’s web site.
A video has also been released of the first lecture of the course :
In the first few minutes, Steve uses HttpWatch running in Firefox to compare the performance of competing pairs of web sites including MySpace and Facebook, MSN and AOL, and the Google and Yahoo search engines.

The video link is broken. I have already reported it to Standford team. Webmasters pl. look into it.
