I run Nextcloud of an NAS appstore. NAS is Asustor Drivestor 4 gen2 - Realtek RTD1619B CPU with 2GB non-expandable DDR4 ram. NAS runs couple of other services like Vaultwarden, Radarr, Sonarr, Uptime Kuma and maybe something else, I dont remember. NAS runs at around 10% CPU and 50% RAM at all times.

Nextcloud isntance is AIO and I have no choice in what type it is. There also are no other good file hosting services but Nextcloud on the app store.

Now the experience: It is slow. Slower than say Google Drive. Login page loads slow but not too slow. I would describe it as sluggish. Like if you run windows 98 file manager on a 5400rpm old drive and you just want to copy couple of files. I went to admin panel and disabled all junk that I will definitely wont run in future. That made it bit faster than before. It works but could be much snappier. Maybe in near future I will move to Opencloud or Owncloud or whatever other services that are similar experience to Nextcloud are.

In my defense, I barely use Nextcloud. It is a nice-to-have option to upload any files that I may find useful to save or/and access later. Therefore, I want to note that sluggishness of Nextcloud doesn't bother me. But I wish it would be as snappy as Immich is.
