I have a simple Drupal 7 site. There is not much content or modules installed on the site. In fact, the site is fairly new. All of a sudden, every page is loading ridiculously slow. It was fine last week. The site and MySQL database reside on a server within my company's intranet. It is only being accessed internally. I have several sites and MySQL databases on the same server and they are running just fine. Again, this is all of a sudden. It's really weird.
Anything I could try to resolve this?
