This is my first real dive into hosting a server beyond a few Docker containers in my NAS. I've been learning a lot over the past 5 days, first thing I learned is that Proxmox isn't for me:

So now I'm running headless Ubuntu and having a much better time! I migrated all of my Docker stuff to my new server, keeping my media on the NAS. I originally set up an NFS share (NAS->Server) so my Jellyfin container could snag the data. This worked at first, quickly crumbled without warning, and HWA may or may not be working.
Enter the Jellyfin issue: transcoded playback (and direct, doesn't matter) either give "fatal player error" or **extremely **slow, stuttery playback (basically unusable). Many Discord exchanges later, I added an SMB share (same source folder, same destination folder) to troubleshoot to no avail, and Jellyfin-specific problems have been ruled out.
After about 12hrs of 'sudo nano /etc/fstab' and 'dd if=/path/to/nfs_mount/testfile of=/dev/null bs=1M count=4096 status=progress', I've found some weird results from transferring the same 65GB file between different drives:
NAS's HDD (designated media drive) to NAS's SSD = 160MB/s NAS's SSD to Ubuntu's SSD = 160MB/s NAS's HDD to Ubuntu's SSD = .5MB/s
Both machines are cat7a ethernet straight to the router. I built the cables myself, tested them many times (including yesterday), and my reader says all cables involved are perfectly fine. I've rebooted them probably a fifty times by now.
NAS (Synology DS923+): -32GB RAM -Seagate EXOS X24 -Samsung SSD 990 EVO
Ubuntu: -Intel i5-13500 -Crucial DDR5-4800 2x32GB -WD SN850X NVMe
If you were tasked with troubleshooting a slow mount bind between these two machines, what would you do to improve the transfer speeds? Please note that I cannot SSH into the NAS, I just opened a ticket with Synology about it.
Here's the current /etc/fstab after extensive Q&A from different online communities
NFS mount: 192.168.0.4:/volume1/data /mnt/hermes nfs4 rw,nosuid,relatime,vers=4.1,rsize=13>
SMB mount: //192.168.0.4/data /mnt/hermes cifs username=_____,password=_______,vers=3.>
Great answer, thank you. To your point, I tried to disable the Tailscale service on my Ubuntu machine and the consequences were bad enough that I'm going to try to avoid Tailscale as much as possible. In disabling it, it also shut down open-ssh, so I had go to the machine with a keyboard and monitor (gross). Re-ran iperf3...while still a bit lower than I'd expect, I don't think I have any room to complain here all things considered.
Now it looks correct. If you have a Gigabit capable switch/router, and 100Mbps seems wrong, you should check your negotiated link speed on your Ethernet interface with something like
ethtool [your_interface] | grep Speed100Mbps is obviously low if you have a Gigabit router. Either way, you should have your jellyfin setup working without issue now.
"Speed: 1000Mb/s". I was under the impression that my HDD (Seagate EXOS) would be roughly double that with some to spare.
Sad to report it is not working. Instead I'm getting a different error every time I try to play media
Does the other end also say 1000Mb/s? Something is limiting it to 100Mb/s
"The other end"? As in my NAS? Because I can't check that machine due to lack of SSH
Does the hardware specification note a 100mb or gigabit port?
it's full duplex
Irrelevant here, it's speed that's cooked
Depending on how this all was built and configured while Tailscale was running, you may need to take some steps to "undo" some things, like re-mounting your network mounts with the proper IPs (auto discovery may have messed things up).
What are the errors you're getting?
Oh sorry, nothing network related (as far as my novice ass can tell). I'm talking about my Jellyfin containers. Tons of excuses related to things that haven't changed
