Hello, I'm using CentOS 8 x86_64 for hosting a WordPress website. My sever has 4GB RAM with 4 CPUs. It is a VM server. I did an analysis: https://pastebin.fun/uaIn8IJvxn And as you see the php-fpm pool processes using more than %80 of server memory. Why? My WordPress website has just a few pages. In "/etc/php-fpm.conf" file, some options like "pm" and "pm_max_children" don't exist and "process.max = 128". What is wrong? Thank you.
