Actually for nextcloud local caching APCu is recommended and seems to perform best. It should also work, if php-apcu module is installed.

As far as I understand from your config, your nextcloud is running and using only one server? In this case distributed memcache is useless, if I am not completely mistaken ;). So you can just remove `'memcache.distributed'` line and `'memcached_servers'` array completely from your `config.php` and things should run just the same.

As mentioned, ask your webhost for php apcu, and use `'memcache.local' => '\OC\Memcache\APCu',` in case.

Next thing would be transactional file locking with redis: [https://docs.nextcloud.com/server/10/admin\_manual/configuration\_server/caching\_configuration.html#id4](https://docs.nextcloud.com/server/10/admin_manual/configuration_server/caching_configuration.html#id4)

If redis is installed and configured i.e. as this:

> /etc/redis/redis.conf  
> port 0  
> …  
> unixsocket /var/run/redis/redis.sock  
> unixsocketperm 770

you could use

> ```
> .../nextcloud/config/config.php
> 'filelocking.enabled' => 'true',
> 'memcache.locking' => '\OC\\Memcache\\Redis',
> 'redis' => array (
> 'host' => '/var/run/redis/redis.sock',
> 'port' => 0,
> 'timeout' => 0.0,
> ),
> 
> ```

to enable it for nextcloud.
