This week we had the pleasure of having Mark Finkle from Tumblr with us, sharing his holistic view on performance approach, and the relevance of framing it from a UX standpoint. That’s why real-user monitoring (RUM) is fundamental to understand what users are experiencing.

Mark then takes us to some performance challenges he has seen at Tumblr and shares a few techniques they are using, for example playing with image and GIF formats for optimal performance. Finally, Mark shares a superb idea on how to use the efforts to build a lite version to improve the original app itself. Hope you enjoy the conversation as much as we did!
