Nextcloud version (eg, 20.0.5): 23.0.2

PHP version (eg, 7.4): 7.4
The issue you are facing:
I had some physical problems with my bootdrive so I had to reinstall Ubuntu on a new drive.
I luckily had my documentation up to date so I was able to reinstall quickly and since i did backups of my mySQL database I was also able to restore the database without any dataloss (eg. calendar entrys or tasks) via https://docs.nextcloud.com/server/latest/admin_manual/maintenance/restore.html. So success there.
But i noticed that the system is responding pretty slowly compared to before. I DO have switched from an SSD to a HDD since it was available and performance was not a primary concern for my home installation. But it is so slow it even times out sometimes so clients (2 Desktops and 3 Android clients) get disconnected.
So i tried to dig a bit and i think this has sth. to do with database syncing:
iotop reports 99% usage by jdb2 for very long periods of time which seems kind of odd:
Total DISK READ: 0.00 B/s | Total DISK WRITE: 1435.99 K/s
TID to ionice:

1200 be/4 mysql 0.00 B/s 300.73 K/s 0.00 % 2.35 % mysqld [ib_pg_flush-2]
3252 be/4 mysql 0.00 B/s 15.04 K/s 0.00 % 1.83 % mysqld [connection]
This only happens when apache2 is running and the only site i am serving is nextcloud. And nextcloud is also the only database that i am running.
What throws me off a bit (besides the 99%) is that there is no DISK READ but so much DISK WRITE. If syncing is done from memory (I have setup as advised in https://docs.nextcloud.com/server/latest/admin_manual/installation/server_tuning.html, so e.g. caching is activated) i do not get why there should be that much DISK WRITE when actually nothing changed on any client …
Also there is enough RAM (16GB currently, will pull out 8GB soon since not needed), as also shown by top:

i googled a bit and found this answer on serverfault.com: linux - High server load - [jbd2/md1-8] using 99.99% IO - Server Fault
So i enabled debug tracing and got the following output:

I am not sure what to do now. I do not even undertand what i did with the debug there tbh.
I thought about build up a new nextcloud DB, Add the users manually, restore calendar and contacts from backups using the WebGUI and then rescan the data directory for the users to restore the “real” data. And then reshare the folders/files and alike. Would that help? Any other suggestions?
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- mess up your bootdrive
- reinstall nextcloud on new drive
- recover database as shown in https://docs.nextcloud.com/server/latest/admin_manual/maintenance/restore.html
- get high I/O from jdb2
