Drupal 10 cache system: Optimizing your website performance
![drupal drupal](/sites/default/files/2024-05/drupal_digitalprojex_0.webp)
Implementation of an efficient cache system is fundamental to optimize your website's performance. Among the available options for developing these systems in Drupal, Redis, Memcache, and Varnish stand out as three powerful systems that can be integrated with Drupal to speed up page loading and improve the user experience.
Redis offers excellent speed and scalability, with robust community support and regular updates ensuring optimal performance. On the other hand, Memcache, despite having a less active development community, remains a valid option for enhancing caching in Drupal 10.
As for Varnish, although it was popular in previous versions of Drupal, it is not compatible with Drupal 10. Therefore, at DigitalProjex, we recommend using the two options mentioned above to maximize your website's performance in Drupal 10.
Redis
To use Redis as a cache system in Drupal, you need to follow several key steps: installing Redis, configuring Drupal to use Redis, and finally, verifying to ensure everything is working correctly. Here's how to do it, assuming you already have Redis installed and running:
- Install the Redis module in Drupal. This module has active community development, with its latest version released on June 23, 2023.
- Configure Drupal to use Redis:
Edit your settings.php file to configure Drupal to use Redis as the cache backend. Add the following lines to the end of the file:
// Add to the end of settings.php
$settings['cache']['default'] = 'cache.backend.redis'; // Use Redis as the default cache backend.
$settings['redis.connection']['interface'] = 'PhpRedis'; // Use PhpRedis.
$settings['redis.connection']['host'] = '127.0.0.1'; // The IP where Redis is listening.
$settings['redis.connection']['port'] = 6379; // The port Redis is listening on.
Clear Drupal cache. To verify the Redis integration, access the Drupal reports page, where you can see a brief report on Redis usage.
Memcache
To use Memcache, follow these steps:
Install the Memcache module on your Drupal site. This module has a less active community, but it's still valid. Its latest stable version was released in August 2022.
Configure Drupal to use Memcache:
Edit your settings.php file to configure Drupal to use Memcache as the cache backend. Add the following lines to the end of the file:
$settings['memcache']['servers'] = ['memcached:11211' => 'default'];
$settings['memcache']['bins'] = ['default' => 'default'];
$settings['memcache']['key_prefix'] = '';
$settings['cache']['default'] = 'cache.backend.memcache';
To verify the Memcache integration, access the site's reports page, where you can see a brief report on Memcache usage.
Leveraging the cache system in Drupal 10 with Redis and Memcache will enable you to provide a fast and efficient user experience.
