To improve Core Web Vitals and loading speed, establish performance baselines using Lighthouse, identify bottlenecks like LCP and CLS, and apply image optimization, code splitting, and caching configurations to reduce load times and enhance interactivity.

The best way to diagnose slow website performance is to run baseline audits with Lighthouse or WebPageTest to track Core Web Vitals, identifying specific bottlenecks such as large images, render-blocking resources, or heavy JavaScript bundles affecting runtime performance.

Fix high LCP and CLS metrics by optimizing asset delivery through image optimization, minimizing render-blocking JavaScript and CSS, and implementing stable layout practices to improve loading speed and visual stability for your web application.

Yes, you can use code splitting to reduce initial bundle size and implement caching strategies to optimize asset delivery, systematically improving runtime performance and loading speed across web projects of various sizes.

You do not strictly need WebPageTest; you can establish a performance baseline for your website using Lighthouse or PageSpeed Insights to measure Core Web Vitals and identify top bottlenecks before applying deterministic optimization workflows.
