Performance Measurement at Koydo (May 2026)
How Koydo measures performance against its public AIO floor — what's collected, where to view the numbers, and how synthetic vs. real-user data are reconciled.
Vercel Speed Insights collects Real User Monitoring (RUM) on every koydo.app page automatically. Synthetic Lighthouse runs supplement RUM via Google PageSpeed Insights for spot-checks. The two are reconciled by treating RUM p75 as the authoritative measurement and PSI as a regression alarm.
The Koydo AIO performance floor
Per Koydo's AIO Citation Doctrine, every public page on koydo.app must hold the following at p75 of real-user traffic: TTFB under 1 second, LCP under 2.5 seconds, CLS under 0.1, and INP under 200 milliseconds. The floor exists because AI assistants do not execute heavy client-side JavaScript and because slow pages get downranked by both Google and the AI-assistant pipelines.
Real-user monitoring (authoritative)
Vercel Speed Insights is enabled on koydo-app and collects Core Web Vitals on every page load from every visitor. The collection is automatic, requires no per-page instrumentation, and is privacy-respecting (no personally-identifying data leaves the browser). p75 numbers become meaningful once a route accumulates roughly 1,000 page views, which most routes will reach within the first week of traffic post-deploy.

Synthetic spot-checks
Google PageSpeed Insights provides on-demand Lighthouse runs against any public URL. PSI is useful before a deploy goes out, when a single page is suspected of regressing, or for one-shot audits. PSI is run from Google's infrastructure, not from a real-user device, so the numbers are not directly comparable to RUM. They are best used as a relative regression detector ('this deploy scored 92 vs the baseline 89; investigate').
Unauthenticated PSI requests are quota-limited to roughly 25 per day per IP. A Google Cloud project with the PageSpeed Insights API enabled and a real API key removes the quota constraint for sustained measurement.
Citing this note
Marketing copy that references Koydo's performance posture should link here rather than to PSI or Vercel directly, because both of those surfaces require login or have rate limits. This note is the public-facing summary.
