Boomerang: How fast do users think your site is?

As a web developer, you probably care deeply about the performance, security, accessibility and internationalisation aspects of your site. You do a lot of testing during development to make sure your web site follows best practices. Tools like YSlow and PageSpeed help you identify and fix performance problems during development, but it's still hard to tell how your site performs from your end user's point of view.

Are your users on dial-up, wireless or broadband? Do they have fast computers, are they on a shared network, what else do they have installed that can slow down their browsing experience? It's almost impossible to simulate all conditions that a user will experience your site through, but it is possible to measure what they experience.

This talk will show you how to use the Boomerang library to test your site's performance from your user's point of view. At the end of this talk, attendees will be able to measure the perceived performance of their sites.
