Website tester FAQ

What does this website tester check?+
It compares your current page with a test version where eligible asset URLs are replaced with Smooth CDN URLs. The report shows page load times, waterfall charts and asset size savings.
Why does it show 1st load and 2nd load?+
The first load shows how the page behaves without a warm browser cache. The second load helps show what changes once repeat visits can reuse cached files.
What should I look for in the waterfall?+
Look at when assets start loading, how long they take and whether the Smooth CDN version finishes earlier overall. The waterfall is meant to make timing differences easier to spot than a single score.
Is this a general performance score?+
No. It focuses on asset delivery: file weight, browser load timing and the difference between the original page and the Smooth CDN test version.
Do I need to create an account?+
No. The tester runs without account setup and only reads public files.
Will Smooth CDN change my website?+
No. The test only reads public files from the URL you provide. It does not modify your page or its hosting configuration.
