Sergey Chernyshev we'll talk about the challenges of capturing accurate metrics around speed of user experience & how instrumenting your application using UserTiming API can help. He will give a brief overview of automated metrics that are captured by the browser & show how custom metrics, specific to features of your user interface can help your teams better relate to these numbers & help more directly align them with user interface optimizations.
Sergey will show how to use native UserTiming API to mark specific events & measure differences between these marks on Performance Timeline. He will also introduce UX-Capture JavaScript library to help simplify & unify this instrumentation across your site. We will also look at debugging process using Chrome Developer Tools & how metrics captured with UserTiming API can be automatically picked up by open WebPageTest tool & other synthetic & RUM monitoring tools. We'll also touch on how UX Capture library can be used to calibrate RUM accuracy using synthetic video analysis.
