This one's your go-to when a Magento 2 store is dragging and you need to figure out why. It walks you through systematic performance profiling using Blackfire, XHProf, and New Relic, then helps optimize everything from slow database queries to Core Web Vitals. The strength here is the structured approach: baseline metrics first, identify bottlenecks through actual profiling data, prioritize fixes by impact, then validate with testing. Covers both frontend optimization (JavaScript, CSS, images) and backend tuning (query optimization, caching strategies, resource management). Good for when you're past basic fixes and need a methodical investigation into what's actually killing performance at scale.
