6 years ago I'm running this container on a Synology NAS and just after installation the Synology Web GUI states a memory allocation of about 500 MBytes of RAM.

6 years ago In the initial container version i used the default performance settings for Nginx, PHP-FPM and Parsoid. While Nginx and PHP-FPM have dynamic management of worker processes, Parsoid can only manage a static number of workers.
However the default settings that were used were targeting more high availability setups. Since for such setups i recommend manually tweaking and mounting the configuration files, i decided to setup the default values for a minimal usage like in a NAS.
As result i introduced the new environment variables PHPFPM_WORKERS_START, PHPFPM_WORKERS_MIN,PHPFPM_WORKERS_MAX and MEDIAWIKI_PARSOID_WORKERS.
The default number of PHP-FPM worker processes that will initially be startet was reduced from 10 to 1. The default number of Parsoid worker processes that will initially be startet was reduced from 6 to 1.
This reduces the number of processes in the container and therefor affects the memory usage when idle or in low usage.

Short question: How much memory does the the container use in average. I extended the image with composer und the chameloen skin and now it uses about 380 MB of RAM.
