Nevermind, I am an idiot. You're comment gave me thought and so I checked my testing procedure again. Turns out that, completly by accident, everytime I copied files to the LVM-based NAS, I used the SSD on my PC as the source. In contrast, everytime I copied to the ZFS-based NAS, I used my hard driver as the source. I did that about 10 times. Everything is fine now. THANKS!

Both machines are easily capable of reaching around 2.2Gbps. I can't reach full 2.5Gbps speed even with Iperf. I tried some tuning but that didn't help, so its fine for now. I used iperf3 -c xxx.xxx.xxx.xxx, nothing else.
The slowdown MUST be related to ZFS, since LVM as a storage base can reach the "full" 2.2Gbps when used as a smb share.
Its videos, pictures, music and other data as well. I'll try playing around with compression today, see if disabeling helps at all. The CPU has 8C/16T and the container 2C/4T.
The disk is owned by to PVE host and then given to the container (not a VM) as a mount point. I could use PCIe passthrough, sure, but using a container seems to be the more efficient way.
I meant mega byte (I hope that's correct I always mix them up). I transferred large videos files, both when the file system was zfs or lvm, yet different transfer speeds. The files were between 500mb to 1.5gb in size
I don't think it's the CPU as I am able to reach max speed, just not using ZFS...
Good point. I used fio with different block sizes:
fio --ioengine=libaio --direct=1 --sync=1 --rw=read --bs=4K --numjobs=1 --iodepth=1 --runtime=60 --time_based --name seq_read --filename=/dev/sda
4K = IOPS=41.7k, BW=163MiB/s (171MB/s)
8K = IOPS=31.1k, BW=243MiB/s (254MB/s)
IOPS=13.2k, BW=411MiB/s (431MB/s)
512K = IOPS=809, BW=405MiB/s (424MB/s)
1M = IOPS=454, BW=455MiB/s (477MB/s)
I'm gonna be honest though, I have no idea what to make of these values. Seemingly, the drive is capable of maxing out my network. The CPU shouldn't be the problem, it's a i7 10700.
Tubearchivist works well for me and integrates with jellyfin.
Tubearchivist works great for me. Downloader, database and player, all in one. Even integration with jellyfin is possible, not sure about plex though.
Ah, thank you for clearing that up, much appreciated!
Excellent, I'll probably do that then. If I think about it, only one container needs write access so I should be good to go. User/permissions will be the same, since it's docker and I have one user for it. Awesome!
Ah, I did not know that. So I guess I will create several VLANs with different subnets. This works as I intended it, trafic coming from one VM has to go through OPNsense.
Now I just have to figure out, if I'm being to paranoid. Should I simply group several devices together (eg, 10=Servers, 20=PC, 30=IoT; this is what I see mostly being used) or should I sacrifice usability for a more fine grained segeration (each server gets its own VLAN). Seems overkill, now that I think about it.
