Optimizing Nextcloud

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 = 8
opcache.max_accelerated_files = 10000
opcache.memory_consumption = 128
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,

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',
  '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,
  ),

Example Compose

      - /path/to/appdata:/config
      - /path/to/data:/data
    restart: unless-stopped
    depends_on:
      - mariadb
      - redis
      - imaginary
  imaginary:
    image: nextcloud/aio-imaginary:latest
    container_name: imaginary
    restart: unless-stopped
  redis:
