RUM isn’t just for page level metrics anymore. Thanks to modern browser updates and new techniques we can collect real user data at the object level, finding slow page components and keeping third parties honest.

In this talk we will show you how to use Resource Timing, User Timing, and other browser tricks to time the most important components in your page. We’ll also share recipes for several of the web’s most popular third parties. This will give you a head start on measuring object level performance on your own site.
