God awfully slow upload speed after upgrading to nextcloud 19

Hi all

These last few days I’ve been upgrading my nextcloud setup.

For starters I upgraded the instance to nextcloud 19 and fixing any errors that came up in the overview.

Next to that I also setup a Qnap NAS where the new nextcloud data folder resides (migration went succesful)

On my desktop I also upgraded the client to the 3.0.0 version.

When setting up the client I’ve noticed that my upload speed is really really slow to the point that it’s unusable:

It upload about 1MB every 5 minutes.

I have no real clue what’s the issue. I first thought it was the cache so I setup APCu but it had no real improvements. Admin and /var/www logging don’t really seem to point out anything.

I also have Plex running and it doesn’t have any issues so i don’t think it has to do with the network share.

My setup is as follows:
Raspberry pi4 with nextcloud pi running of a 64GB Sandisk Extreme SD card.

Nfs connection to network share using fstab automount.

NAS and Pi are connected via Cat7 ethernet cables using a switch (so network shouldn’t be the issue either).

Hoping for someone to help me with this. Been pulling my hair on this one
