Wordpress WordPress not using memcache and memcached warnings

Hi there,

For testing, I install a plugin to see how my WordPress sites are preforming. The plugin is Query Monitor by John Blackbourn and it gives some nice information.

It also told me that WordPress is not using memcache and memcached

Code (Text):

Object Cache

98.9% hit rate (24,553 hits, 282 misses)

External object cache not in use

[LIST]
[*]The Memcache extension for PHP is installed but is not in use by WordPress
[*]The Memcached extension for PHP is installed but is not in use by WordPress
[*]The Redis extension for PHP is installed but is not in use by WordPress
[/LIST]
Opcode cache in use: Zend OPcache

But after installing this plugin MemcacheD Is Your Friend, an ancient one, it seems to be resolved. There is also a forked one here with some commits here on wpbullet/memcached-is-your-friend

---

Code (Text):

[SIZE=4]Object Cache[/SIZE]

100.0% hit rate (23,189 hits, 4 misses)

External object cache in use

Opcode cache in use: Zend OPcache

Now the question: Can we use it or not. Seems to be interesting.
Now I can see the results of my Memcached

 

Currently, I use on most of my sites Fastcgi_cache (PHP-FPM) on with the nginx cache and with the wp-rocket, but it sometime gives strange effects backend. Admin panel completely mixed up until I get it done to clear the cache.

Will do some testing on my test domain and with duplicator to see what gives the best result

As I see now, the Redis Object Cache is more actual than what I mentioned the wpbullet/memcached-is-your-friend

I stopped using Redis after my issues with a theme, but that was resolved with a little edit in the wp_updater script.
