What Hosting Drupal Actually Requires: PHP, Database and Memory Floors
Drupal's reputation for slowness often stems from hosting choices rather than the software itself, as sites are frequently deployed on plans built for simple brochure sites. Drupal expects a current PHP version, a recent database, a real cache backend, shell access and a proper cron setup, which cheap shared hosting often fails to provide. Its published PHP and database requirements differ by release, with Drupal 11 and 12 demanding newer versions than Drupal 10. Several PHP branches approach end of security support around late 2026, when Drupal 10 also reaches end of life and Drupal 12 is released. Drupal's documented minimum is 64MB of PHP memory, though 128MB to 256MB is typical in production.
