In today's episode, we’re diving deep into web performance — and not just looking at numbers, but learning how to understand them and act on them.

I’m joined by Maxi, and together we break down:

• What Core Web Vitals are (LCP, FID, CLS) and why they matter beyond just SEO
• How to measure your site’s performance using tools like Lighthouse, PageSpeed Insights, and field data from real users
• What the baseline thresholds mean — and how slow performance actually feels to users
• How to investigate and fix underperforming metrics — including practical tips for debugging Largest Contentful Paint (LCP) problems
• Why JavaScript is often the hidden villain behind slow pages — and what you can do to manage bundle size and third-party scripts
