Tracking Page Speed

by Sergey Chernyshev

Published June 8, 2017 in Programming

Over the years, multitude of metrics were developed, from Time To First Byte and Page Load Time all the way to more modern and sophisticated ones like Time to First Paint, ATF, Speed Index and Frames per Second. One challenge with current performance metrics is that they all are proxies for user experience and do not translate directly into user satisfaction and business gains, but with each new metric we are getting closer to measuring what matters. Sergey will talk about pros and cons of technical metrics historically used to monitor performance, describe two core methods or measurement/monitoring (synthetic and RUM) and introduce latest developments in tracking user-centric metrics.
