I meant the entire libapache2-mod-php module is loaded into ram for every access to every file no matter if it's a non-php static file or a php file. Each apache process (+ mod-php) is from 20Mb to 100Mb regardless of whether it's about to parse a PHP script or not. A nginx instance is about ~9Mb and delivers a static file up to twice as fast as apache with mod-php (according to ab testing I did 1/2 dozen years ago). I find php-fpm usually runs at 3Mb to 30Mb but sometimes up to 100Mb for Wordpress with massively complex themes and plugins. So nginx + php-fpm generally uses less ram than apache + mod-php for PHP scripts but up to 10 times less ram for static files (css, js, images) and static files (until cached) far outnumber PHP script access. ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
