 * Hello Support,
   Since using WP Optimize on 4 websites, my server has been overloaded.
   It was struggling, so I cleared a load of junk and stopped my backups to allow
   space, but today it’s in the red zone again. Not the struggle it had before clearing
   junk, but it isn’t good either. I have turned off the minify css because my sites
   work better and faster. Do you have any ideas what it could be?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fserver-overload-9%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi,
 * Thanks for contacting us! Can you let me know if you are using the Page Cache
   Preloader on these sites in WP-Optimize > Cache > Preload > Schedule Preloader?
 * Based on the description it sounds like the preloader might be running on these
   sites and causing an issue with resources.
 * Let me know whenever you have a moment and we’ll troubleshoot from there!
 * Thank you!
