Page turning speed test?

Question

Performance evaluation

All services only test 1 page , and I need an ergonomics assessment.
if you compare different sites, purely subjectively, one works better: it flips faster - and the other one flips 3 times slower. I don't know, I didn't compare page volumes, I want to get all these statistics ready.
but the tools.pingdom.com or gtmetrix.com services give a higher rating to the site that actually has problems with scrolling.
tell me if there is such an analyzer? if not, then how to test this speed - with what utilities?

Answer 1

What does flipping mean? Like, the server took it, spat on his finger and turned the page - does it need to be measured?
Seriously, most likely you mean page loading speed. And the services you mentioned just analyze it.
