Is site loading speed bad for SEO?

Question

Google

Hello everyone, a question for SEOs, I want to know if the site loading speed greatly harms the position of the site in Google? For the last two days, I have been watching how the site for the desired top request is either higher by 4 positions or lower by 2 and the position changes back and forth all day long, the site loading speed was 51/100, Google showed, but the problem is that in the DC of my country, the speed on the outside is The rest of the world is a low (256kb / s) site for the internal network of the country, there is an excellent download on the internal network, 100MB is given and there are no problems with downloading. But here Google is an outsider and therefore he thinks that the download is long, so I want to know if it hurts much?

Answer 1

It's not "speed" that hurts, it's SLOW loading. And not only for "SEO", but for users.
What kind of DC/country is this?
And why can't the site be transferred to a normal DC?

Answer 2

Yes, it hurts.

Answer 3

33% - harms SEO (robots analyze speed)
66% - harms users
I advise 2 options (either or both at once):
1. Transfer to a normal hosting
2. Make a SPA and exchange only data with the back-end.
