The Web Performance Landscape in 2024
summary
Sets current numbers and tools against real failures: global device split and browser reach (Chrome ~66% Safari ~18%), median page growth and resource hotspots (~3 MB median page; video and JS drive growth), and extreme third‑party cost observed (320 third‑party requests, >2 MB third‑party JS on some pages). Shows Core Web Vitals adoption gaps, per‑site INP → conversion thresholds varying widely (100–600 ms), and common audit fails like inefficient caching and unused JS so viewers know what to fix first.
