Transfer speed issues on new Proxomox 8.3 setup (lemm.ee)

I recently posted about upgrading my media server and migrating off Windows to Proxmox. I've been following an excellent guide from TechHut on YouTube but have run into issues migrating my media into the new Proxmox setup.

Both my old Windows machine and new Proxmox host have 2.5Gb NIC cards and are connected together with a 2.5Gb switch and running on the same subnet. Following the guide, I've created a ZFS pool with 7x14TB drives and created an Ubuntu LXC which is running Cockpit to create Samba shares.

When transferring files from Windows, I'm only seeing 100MB/s speeds on the initial transfer and every other transfer after that caps out at >10MB/s until I reboot the Cockpit container and the cycle completes.

I'm not very knowledgeable on Proxmox or Linux but have run an iperf3 test between Windows > Proxmox and Windows > Cockpit container and both show roughly 2.5Gb transfer speeds yet I am still limited when transferring files.

Googling the issue brings up some troubleshooting steps but I don't understand a lot of it. One fix was to disable IPv6 in Proxmox (I dont have this setup on my network), which was successful, but didn't fix anything. I no longer see the interface when doing an 'ip a' command in Proxmox, though I do still see it when doing it in the SMB container.

Does anybody have any experience with this that can offer a solution or path toward finding a solution? I have roughly 40TB of media to transfer and 8MB/s isn't going to cut it.

What's the benchmark on the disks? Are these SAS drives?

Can you elaborate on what you mean by benchmarks? These are all SATA drives

[–] possiblylinux127@lemmy.zip 1 points 12 hours ago (1 children)

That's your problem. You need enterprise drives to do faster speeds

I don't believe that's my issue as none of the drives are even reaching 50% utilization on either end and it also doesn't explain why initial transfers hold at a consistent 100MB/s but every transfer after that limits to >10MB/s until I restart the samba service on the container.

Can you post a benchmark to confirm?
