Observing where latency occurs in every layer of your stack is critical to understanding its performance, and that can be especially challenging when you’re building your own open source observability solution to maintain your front end. There’s less of a latency budget than you think. Measuring delays from network requests and browser operations are necessary but they do not tell the whole performance story. Knowing what delays your users are actually experiencing (and where) gives you actionable views into why your app is hung up, and how to foster your best experience possible.
