Noise Canceling RUM - We Love Speed 2023

Noisy Real User Monitoring (RUM) data can ruin your day! We introduce a fresh concept called “Human Visible Navigations” (HVN) to tackle this risk; we focus on the experiences you actually care about when talking about the speed of our sites.

Presentation given at We Love Speed in Paris, May 10th 2023
