I know it’s advised by MainWP not to use cache for a MainWP (only) Dashboard website.
However, I am curious if some people out here are using Redis cache for their MainWP dashboard site. Since Redis can speed up the MainWP Dashboard site WP-Admin it seems very useful when having a lot of websites in MainWP?
I’m using this setup with Redis Object Cache – WordPress plugin | WordPress.org without any problems. Though you have to install/configure php-redis module on the backend to make use of it (sudo apt-get install php-redis)
Let me know if you run into problems… happy to help.
