Redis

Speed Up Your WordPress Database

Using a persistent object cache such as Redis cache allows for the reuse of cached objects rather than requiring the MySQL database to be queried a second time for the same object. The result is that Redis can reduce the load on a website's MySQL database, simultaneously decreasing the response time of the site and increasing the site's ability to scale and handle additional traffic.

File-backed caching (as properly configured with WP Super Cache or WP Rocket) will always be faster than using Redis. We don't recommend using Redis for WordPress caching unless you are an expert sysadmin who understands when and why to use it.If you have installed Redis on your Wordpress app, you will also need to install the Redis Object Cache plugin to use Redis with WordPress. Please view tutorial for help.

Only use Redis on a single-app server. The data stored in Redis will be accessible to all apps on your server, so it is not secure to use Redis on a server with more than one app.

How to activate Redis on your server

In the Redis page, click the cog icon. Then click the popup Install Redis button. It will take a few minutes for the installation to complete.

Once installed, if you hover your moouse on the red dot, it will show Redis is running. Gray dot means not running. You can also see the Redis Memory usage, CPU usage and Redis version installed on your server.

Click the cog settings icon. In the popup tab, you can uninstall, stop or restart Redis.

Install the Redis Object Cache plugin
