What the numbers say
- AWS fails Core Web Vitals on Largest Contentful Paint (3.2 s, good is 2.5 s or less).
- Time to first byte is 1.2 s, so most of the LCP time is spent after the first byte: loading the main image, fonts or scripts.
- Among 16 hosting and cloud sites we track, AWS has the 12th fastest LCP.
- INP has worsened by 29 ms over the last 25 weeks, from 104 ms to 133 ms.
Keep a site like this from getting slower
Real-user data shows a regression weeks after it ships. Vitalgate runs Lighthouse on every pull request and fails the check when a change breaks budgets like these: LCP ≤ 3.2 s, CLS ≤ 0.10, FCP ≤ 2.8 s.
