Redis seems to be the solution for caching nowdays.
Hopefully there will be a full functioning redis included. The current 'redis' & 'memcached' is for show, since they both does not work.

Object Cache Module of the WP Optimization Suite has been released for CloudLinux OS Solo. Solution for CloudLinux OS Shared PRO will be available in about a month.

WP Optimization premium paid by user does not completely respond to this request :
- Redis cache needs to be made available to all users who want to use it and not charge users to use it (we need a per server licence).
- The Redis cache needs to work for all site applications. We need it to provide redis settings instead of configuring a WordPress plugin so customers can use it for custom applications and so it can also be used in other WordPress plugins, like LiteSpeed Cache plugin for example. -

I have some clients asking about this and are eager to use it.

Any News regards WPOS released on stable for shared pro?
Also It should support Litespeed out of the box too. -

Is there any news on this ? Is CloudLinux likely to have a cPanel redis plugin sometime in 2019 ?

+1 for a redis instance per account protected with private ports.

I would like to see automatically set up redis instances for each account that have it allowed in the package limits. Should be with a socket at /tmp/redis for example.

Yes, stupid of me, I was searching the docs but could not find anything about it, so I assumed it was already inside the package *FACEPALM*.
I had memcached installed, but it was not enabled. It acted like it worked but did not save anything, and redis said server went away, so I thought it kept crashing :P
I want to use the caching for a shared hosting, but is it safe to use? I wouldn't want customers to share the same space with other people.
I installed redis with this: https://nixtree.com/blog/install-redis-daemon-and-redis-php-extention-on-centosrhelcpanel/

What do you mean for the show? Are you talking about PHP modules? They are just modules, you still have to run daemon somewhere.
