Measure the response time of the page display (waitForLoadState)

Hi Everyone,

The goal is to measure the response time of the page display.
All the requests (56 in my case) making up the page must be completed.

I tried the methods “page.waitForLoadState(‘networkidle’);” and page.waitForLoadState(‘domcontentloaded’);"

Here is the result: 0 ms → Between t1 and t0

RUN :
var src=page.goto(‘http:// MY URL’, { waitUntil: ‘networkidle’ });
sleep(0.3);
var t0 = Date.now();
page.waitForLoadState(‘networkidle’);
var t1 = Date.now();
console.log("------------------------------->>>>>>>>>>>>>>>>>>>>>>>>>" + t1);
console.log((t1-t0));
console.log("------------------------------->>>>>>>>>>>>>>>>>>>>>>>>>" + t0);

CONSOLE.LOG:
INFO[0010] ------------------------------->>>>>>>>>>>>>>>>>>>>>>>>>1642091416660 source=console
INFO[0010] 0 source=console
INFO[0010] ------------------------------->>>>>>>>>>>>>>>>>>>>>>>>>1642091416660 source=console

It seems that these two methods do not work!
Is there another way to do it?

thanks
