The performance criteria to be evaluated are:

Time to First Byte (TTFB)The time it takes for the web server to start responding with data

Time to First Meaningful Paint (TTFP)The time it takes for the browser to paint the page on the screen

Time to Interactive (TTI)The time it takes for all JavaScript to be downloaded, parsed, and executed
