Reduce CPU replacing prefork with event?

Hi, My server is consuming more CPU than it should, I have optimized it but yet, it is consuming a lot, even more on its peak hours (obviously). I have a lot of sites but all of them are medium but of course, if we add all visitors let's say it has a lot of visitors. Would moving to Event from Prefork help CPU or not?

  Hello, It's difficult to know for sure if moving to the Prefork MPM will help. You may want to try temporarily enabling it and monitoring the server over a period of a few days to see if you notice a change in performance. You can review information about each MPM option at: Multi-Processing Modules - MPMs - EasyApache 4 - cPanel Documentation Thank you.

  Hello, It depends on if you have any existing Apache/PHP modules enabled that rely on the Prefork MPM. For instance, you won't be able to use DSO/Mod_Ruid2 without the Prefork MPM. The following documents show you the differences and requirements: Multi-Processing Modules - MPMs - EasyApache 4 - cPanel Documentation PHP Handlers - EasyApache 4 - cPanel Documentation Thank you.
