About the Page Speed Checker
The Page Speed Checker downloads a page and each resource it references, timing every request. It shows the total time and which stylesheets, scripts and images are slowest, so you know where to optimise first.

Frequently asked questions
Why is my result different from other tools?
Timings depend on where the test runs and network conditions. Compare results from the same tool over time.
What slows pages down most?
Large images, many separate scripts and slow server response are the usual culprits.
Does it measure Core Web Vitals?
No - it measures download times. Use Google PageSpeed Insights for field Core Web Vitals.
