Apache takes too long to load pages, how to fix it?

Question

linux

Installed lamp server on ubuntu server 18.04. Loaded a wordpress site, now if you go to the site by url / then the page loads quickly.
If you try to go to /wp-login.php it loads within 2 minutes, maybe longer. What is the reason?
Also installed phpmyadmin at /phpmyadmin is also loaded for a very long time.

Answer 1

I put on a cap KO
1 Find the reason.
2 Fix it.
Now to the point. This behavior can be caused by various problems, lack of resources for the vps, mysql brakes, incorrect apache + php settings, and much more. Each version must be checked. The information you provided is only enough for guesswork.

Answer 2
