Performance testing for web sites

"Boomerang is a piece of javascript that you add to your web pages, where it measures the performance of your website from your end user's point of view. It has the ability to send this data back to your server for further analysis. With boomerang, you find out exactly how fast your users think your site is." - Yahoo Boomerang. See also its manual here.

Simply, it is a piece of JavaScript code, added to your web page and calculates time difference for two events: window.onload and window.onunload

P.S. on the server side level check out by the way Profile taglib from Coldbeans.
