The Basics

TrueNAS Scale 25.10.1
- Web server and version (e.g, Apache 2.4.25):

Unsure how to check
- Is this the first time you’ve seen this error? (Yes / No):
Yes
- When did this problem seem to first start?
- Since installation`
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
Docker via TrueNAS
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
No
Summary of the issue you are facing:
I have recently installed Nextcloud as an app in TrueNAS scale, I have followed this tutorial (https://youtu.be/1rpeKWGoMRY?si=ctB_QN-IdzY_ecIO).
The web interface is working fine and I am able to access it, however when I upload files via WebDAV mounted in Windows the performance is awful. When I am accessing a SMB share running on TrueNAS I can get 100 MB/s, but on Nextcloud I get barely 10 MB/s.
I have tried looking into this on various threads here, but I am unsure how to attempt what people are suggesting.
The upload speed on the web app is considerably better, I also have the same performance issues in WinSCP.
Steps to replicate it (hint: details matter!):
-
Mount Nextcloud using WebDAV in file explorer
-
Try uploading files, the speed is extremely slow
Configuration
Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Unsure how to do this.
