WordPress loading pages and admin slowly

Hi,

There are some reasons for that https://firstsiteguide.com/reasons-wordpress-site-slow/
Also, you can check your site’s speed here https://gtmetrix.com/ and it will also show you the reasons why your site is slow.

Thanks

Thanks, here’s the GTmetrix results.
PageSpeed: A (95%).
YSlow: B (88%).
Fully Loaded Time: 4.1s.
Total Page Size: 301KB.
Requests: 17.

Seems like the website loads quickly, however really the page loads slowly and the wp-admin page takes forever to load.

I doubled the server’s RAM and the RAM is not overloaded.
I added the W3Total Cache plugin.
I turned off all plugins.

I suspect the webserver is slowing the WordPress website, however not sure how to fix it yet?
