CheckAbout Website Speed Test
Website Speed Test brings the required input, options and result into one focused workflow. Analyze page loading speed and response time. The result changes when the source data or selected options change, so it is easy to run a second comparison.
A practical way to use it is to run a fresh diagnostic after a hosting, DNS, certificate, redirect, content or performance change. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.
The checker uses the public target you enter to make a diagnostic request. Do not place credentials or private access tokens in a URL.
