Configuring Joomla to use Redis

Redis is an open‑source memory object caching system that stores frequently accessed data in RAM. By integrating Redis with Joomla, you can significantly improve site performance and reduce database load. On ruachost.com, Redis is supported on Turbo shared hosting, Turbo reseller, Managed VPS, and Managed Dedicated servers.

Why Use Redis with Joomla?

• Accelerates page load times by caching database queries and API calls.

• Reduces server resource usage.

• Improves scalability for high‑traffic Joomla sites.

• Provides persistent caching across sessions.

Prerequisites

• A hosting plan that supports Redis (Turbo shared, Turbo reseller, Managed VPS, or Managed Dedicated).

• Redis service enabled on your server.

• Joomla version 4 or later recommended.
