About the Website Speed Checker
A website speed checker that measures the round-trip time and the size of the response for a URL you enter.
How to use the Website Speed Checker
- Enter the full URL, including https.
- Run the check.
- Read the timing and the payload size.
What to check
This is a single request from the browser, not a full lab report of every image and script on the page.
Is this the same as Lighthouse?
No. Lighthouse scores a full page load. This check reports the response time and size of the URL you test.
Why is the time different from my own browser?
Distance, caching, and the network between you and the site all change the number.
