Introduction

Configuration

pvn

This configuration is the smallest one we recommended for Drupal 9. It uses a swap file to satisfy the memory requirements of composer. This is OK for a development site. However, since this configuration uses SSD, a swap file may case hardware degradation over time if the site receives heavy traffic, so you should not this configuration on a high traffic production website.

The memory requirements of composer is on the heavy side so you should make sure that there is at least 4 GB of RAM available. If you're using a traditional hard disk you may resolve this by creating swap file to accomodate this. If your VM uses SSD, a swap file may case hardware degradation over time, and you may need to go with a plan with 4 GB of physical RAM.
