What this does not measure

  • Both numbers are synthetic lab runs at different moments. A CDN having a busy afternoon shows up as a difference that is not about your code.
  • It compares lab metrics only. Field data for two URLs is usually not available for both, and showing one beside the other would be misleading.
  • PageSpeed Insights rate-limits us. A comparison that has to wait is reported as a wait, not as a result.
