So what do we measure and how do we measure it? Our most important metric for now is the “First Meaningful Paint” (FMP) https://developers.google.com/web/tools/lighthouse/audits/first-meaningful-paint, tested on a 3G connection on a mobile device. We monitor our perf. with @SpeedCurve@twitter.com (which runs WebPageTest tests in the background).
There is still plenty of room for improvement on the technical side, but I guess the most important thing for us as a team was to get sort of a “performance mindset”, to include the topic in our daily work life and to be open and transparent about the topic.
