My Nextcloud has always been sluggish — navigating and interacting isn’t snappy/responsive, changing between apps is very slow, loading tasks is horrible, etc. I’m curious what the experience is like for other people. I’d also be curious to know how you have your Nextcloud set up (install method, server hardware, any other relevent special configs, etc.). Mine is essentially just a default install of Nextcloud Snap.
Edit (2024-03-03T09:00Z): I should clarify that I am specifically talking about the web interface and not general file sync capabilites. Specifically, I notice the sluggishness the most when interacting with the calendar, and tasks.
I stopped using it because it has an extremely complex protocol, with very large bloat that increases with the number of files, and incredibly sensitive to latency.
When I stopped syncing directories because they would take days to upload and started compressing them so they would finish in 10 minutes, I decided it had to go. (Oh, and it’s extremely sensitive to network problems too.)
I still use Nextcloud for syncing documents and other basic stuff that is relatively simple. But I started getting glacial sync times consuming large amounts of CPU and running into lots of conflicts as more and more got added. For higher performance, more demanding sync tasks involving huge numbers of files, large file sizes, and rapid changes, I’ve started using Syncthing and am much, much happier with it. Nextcloud sync seems to be sort of a jack of all trades, master of none, kind of thing. Whereas Syncthing is a one trick pony that does that trick very, very well.
