Performance

Performance views explain why a journey felt slow or unstable.

What OpenRUM captures

• Core Web Vitals such as LCP, INP and CLS from real Page Views
• Route-level performance context for client-side navigation
• Browser API Request timing that often correlates with UX regressions

How to use it

1. Compare Web Vitals across Release, device or country segments.
2. Open affected Sessions when a Route regresses.
3. Correlate slow or failing API Requests with Issue spikes.

Performance metrics are evidence for investigation, not a separate product. Related: Investigation, API monitoring.
