Optimizing Nextcloud

Warning

Little disclaimer. Some information was copied from virtualize.link, because I find information provided by its author useful. Make sure to check the source or star the repo.

The following is a collection of ways to optimize Nextcloud's performance and responsiveness.

Optimization Steps

Use the LSIO image, not the official
Use the latest tag which includes php8
Enable redis
Use mariadb (alpine) or postgres
Use nextcloud v22 or higher
Use imaginary to speed up thumbnail creation
Add the following to /config/php/php-local.ini

memory_limit = -1
opcache.enable = 1
opcache.enable_cli = 1
opcache.interned_strings_buffer = 16
opcache.max_accelerated_files = 130987
opcache.memory_consumption = 256
opcache.save_comments = 1
opcache.revalidate_freq = 1

Add the following to /config/php/www2.conf

pm = dynamic
pm.max_children = 120
pm.start_servers = 12
pm.min_spare_servers = 6
pm.max_spare_servers = 18

Disable Dark Reader extension on it, if you use it
For Nextcloud to identify filesystem changes, add the following to the config:
```
  'filesystem_check_changes' => 1,
```
Move /config to a fast disk such as nvme and mount it from there
After the initial run move /data/appdata_INSTANCEID to a fast disk such as nvme and mount it from there, add the following under volumes:: (the ID in the directory names will be different)
```
      - /path/to/appdata/appdata_ocytnd8b2l1b:/data/appdata_ocytnd8b2l1b
```

Example Nextcloud Config

Located in /config/www/nextcloud/config/config.php

  'dbname' => 'nextcloud',
  'dbhost' => 'mariadb',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'mysql.utf8mb4' => true,
  'dbuser' => 'nextcloud_user',
  'dbpassword' => 'DATABASE_PASSWORD',
  'trusted_proxies' => ['172.16.0.0/12'],
  'filesystem_check_changes' => 1,
  'memcache.local' => '\\OC\\Memcache\\APCu',
  'memcache.distributed' => '\\OC\\Memcache\\Redis',
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'enable_previews' => true,
  'enabledPreviewProviders' => 
  array (
    0 => 'OC\\Preview\\Imaginary',
    1 => 'OC\\Preview\\Movie',
    2 => 'OC\\Preview\\MP4',
  ),
  'preview_imaginary_url' => 'http://imaginary:9000',
  'redis' => 
  array (
    'host' => 'redis',
    'port' => 6379,
  ),
