 ### Notes
 - [It has been reported](https://github.com/Wonderfall/dockerfiles/issues/37) that this image might not work well with old versions of aufs. Please update aufs to 4.x or later, or use overlay/btrfs as a replacement.
 - HTTP port has recently changed, it's now **8888**. You will have to modify your reverse proxy settings.
+- A Redis sever is now running, so you may want to configure it for file locking cache if your config.php was not generated recently. [For best performance it is recommended by Nextcloud documentation](https://docs.nextcloud.com/server/10/admin_manual/configuration_server/caching_configuration.html#additional-notes-for-redis-vs-apcu-on-memory-caching). Add the following lines to your `config.php` :
+
+```
+  'memcache.locking' => '\OC\Memcache\Redis',
+   'redis' => array(
+        'host' => '/tmp/redis.sock',
+        'port' => 0,
+        'timeout' => 0.0,
+         ),
+```
