Why does my drupal website slow down?

Question

PHP

Hello!

There is a group of sites on cms Drupal. There was a virus attack; after cleaning from viruses, they were updated to version 7.58. From that moment on, I noticed brakes on the sites: the time from the beginning of the page request to the server response is from 7 to 10 seconds. Below is a graph with gtmetrix:

XHProf profiler was connected to the hosting TP; The "PDOStatement::execute" function turned out to be the most gluttonous for the execution time - it took almost 11 seconds. As I understand it, PDOStatement::execute works with the database.

Is it possible to conclude from this data whether the problem is in the site (or even in some particular section of the code) or the problem is in the hosting? I have no experience in using this tool, but I did not find any third-party "crooked" function left after cleaning from viruses or in some additional Drupal module that takes so much time.

Hosting - beget, contacted technical support - they said that the problem was not on their part.

Simple optimization required. Search Google/Yandex.
