How to know the server response time Google PageSpeed ​​is looking at?

Question

Web development

Hello!
There is a task to speed up the site, because. Google PageSpeed ​​swears at him.
I deployed a copy of the site on the local server, but I can’t figure out how to see the server response time in the Chrome developer panel.
I look at the Networking tab -> select the requested url, I see the Timing tab prntscr.com/jj4osn
At first I thought it was TTFB, but then I read that it was wrong, although many confuse ...
Queueing remains - but I'm not sure this is what you need ...
And Maybe Chrome doesn't show this time at all?

If you still want to measure the time for which the server responded to a browser request for the local server (the time from the request to the start of the transfer of html and resources), you can use the Lighthouse extension for Chrome. Install, open the site, call the extension, then leave the performance measurement "Options -> Performance" enabled. You generate a report.
To understand the discrepancies in the indicators, I would advise you to measure the response time on the local (through the extension) and on the combat one through gtmetrix before making changes to the site code.
By the way: in gtmetrix.com there is a layout for download speed - the "Waterfall" tab. With its help, you can understand what affects the speed of loading the site.
The screenshot below shows a problem with hosting - the server responded to the request in 8 seconds.

server response time is TTFB - time to first byte.
it may vary slightly depending on the "speed" between the site server and the server doing the testing.
for Google, it is enough if this indicator is less than or equal to 0.2 seconds.
This indicator is not the main and not the most critical.
it is better to focus on Time to first paint
, it is indicated by a vertical line on the Performance tab

to simplify - the closer this line is to the beginning, the faster According to Google, the site will load.
to move it to the beginning, you need to look at what Google is complaining about.
The advice is usually pretty good. the bulk of the sites will help.
