Response Time Check

Makes one request for the home page of a public site from an AOD Pulse probe and shows how long each phase took. The result is kept for 24 hours.

What is measured

Name lookup, connecting, the secure connection (https only), the wait for the first byte of the answer and the total time. This is a single sample from one location, so run it more than once to see the spread. Redirects are not followed.
