When the interface lags
summary
The talk looks at web performance issues that occur after page load — areas that common benchmarks and most Web Vitals miss — and shows how to use Chrome DevTools to find and diagnose sluggish UI and problematic code paths. It covers practical DevTools techniques to detect and analyze post-load UX performance problems rather than relying only on initial-load metrics.
