Running one web site is hard. Running many sites for a litany of demanding e-commerce customers is a daunting task. That is the world Norm Morrison of eBay Enterprise lives in every day, where he is regularly confronted by problems such as:

  • Is an individual performance complaint an outlier or a trend?
  • Is a performance problem caused by my platform, my customer’s page layout, or a third party?
  • Which objects are causing performance problems today?

In this talk, Norm and Buddy will review techniques and tips for doing root cause analysis with RUM data. At the end of this presentation you will be able to leverage the latest timing APIs in browsers in new ways, to do more than understand whether there is a problem, but also discover how to fix it.
