General recommendations for the best performance

Since AIO is pretty much as optimized as it gets, it is mostly an infrastructural question how fast your Nextcloud performs. In general: much helps much.

General recommendations

• Use SSD storage for everything and no HDD storage and especially no SD-cards or network storage like NFS or SMB (however all are fine as backup storage)
• Run Docker and AIO not in a VM but directly on the server (e.g. Docker Desktop needs 4GB+ additional RAM in comparison to a normal Linux server running Docker).
• Deactivate all optional containers and Nextcloud apps that you do not really need
• For faster previews, it is recommended to set up the preview generator app in order to pre-generate previews
• Do not use Cloudflare (Proxy or Tunnel) as it potentially slows down things by a lot and introduces a lot of problems: https://github.com/nextcloud/all-in-one#notes-on-cloudflare-proxytunnel

Additional recommendations, based on Nextcloud's user count and enabled containers

• Have 1 vCore per active user
  (plus the base system requirement of AIO depending on the enabled containers which is mentioned in the AIO interface)
• Have 1GB RAM per active user
  (plus the base system requirement of AIO depending on the enabled containers which is mentioned in the AIO interface)

Additional recommendations for hosting in home networks

• Have a fiber-optic connection to the outside with the highest available upload rate
• Have a good router that is capable of handling everything that you throw at it
• Connect your server via Gbit LAN-cable and not Wi-fi to the router
• Set up a local DNS-server that allows to automatically connect to the server in the home network via the same domain by using the internal ip-address of the server (see this doc)

Might be worth calling that out Docker Desktop running on Windows is going to add +4 GB to any memory requirements due to the extra overhead of running a VM on the underlying host (unlike when the host is Linux-based):

@szaimen can you move this to the main readme? maybe under a heading like "system requirements" or "hardware recommendations", maybe also add "improving performance"?

The main readme is where I would first look for system requirements. This info here took quite a while to find.

(sidenote: maybe we even need a link from https://docs.nextcloud.com/server/latest/admin_manual/installation/system_requirements.html to the AIO system requirements, because AIO has become the official way to install Nextcloud)

[szaimen]

The system requirements are shown in the AIO interface:

all-in-one/php/templates/containers.twig

Line 606 in 12ec7dc

<strong>Minimal system requirements:</strong> When any optional container is enabled, at least 2GB RAM, a dual-core CPU and 40GB system storage are required. When enabling ClamAV, Nextcloud Talk Recording-server or Fulltextsearch, at least 3GB RAM are required. For Talk Recording-server additional 2 vCPUs are required. When enabling everything, at least 5GB RAM and a quad-core CPU are required. Recommended are at least 1GB more RAM than the minimal requirement.
