I have been having a few issues recently, and I can’t quite figure out what is causing this. My setup:

  • gigabit WAN up and down. Run speed tests regularly and get 800+ mbps up and down.
  • opnsense router VM (proxmox) running on a lenovo m920x. Installed an intel 2x10gbe card.
  • Sodola 10gbe switch
  • TrueNAS server (bare metal) w/ 10gbe serving the media files over NFS, stored on a ZFS mirror.
  • Jellyfin LXC
  • debian LXC running the arr stack w/ qbittorrent
  • NVidia Shield w/ ethernet

First issue is extremely slow downloads on qbittorrent. Even if I download an ubuntu iso with hundreds of seeders will sit around 1 mibps. Media downloads with ~10 seeders, I’ll sit around 200kibps. Running this through gluetun and protonvpn wireguard with port forwarding enabled and functioning.

Second issue I’m having is if I am downloading anything on qbittorrent, and attempt to play a 4k remux on Jellyfin, it is constantly buffering. If I stop all downloads, immediately the movie plays without issue. 1080 files play without issue all the time.

I tried spinning up a new LXC with qbittorrent, and can download ubuntu isos at 30+ mibps locally and not over NFS.

Any idea what could be causing this? Is this a read/write issue on my TrueNAS server? Networking issuing causing the NFS to be slow? I’ve run iperf to the TrueNAS and getting 9+gbps.

    OK so I have done some additional testing:

    • Memtest passed
    • Added the NFS share to the new qbittorrent LXC, and the download speed dropped down to where my primary qbt is. So I believe this means it is related to the NFS share.
    • Connected the NAS to a different switch. No change.
    • Tried connecting to the NFS share through a different NIC in TrueNAS. No change.
    • Migrated the qbt lxc to another proxmox node. No change.
    • Created a new NFS share on a different pool on TrueNAS and made that the download directory for qbt. No change.

    So I believe I have ruled out memory issues, NIC issues, datapool issues, and switch issues.

    The problem is I don’t know exactly when this started.

    I did change out the motherboard on TrueNAS, and just installed the existing NVMe drives into the new motherboard and booted off of them. I did not install a new TrueNAS OS and restore a backup. Could this be an issue?

    Shortly after the motherboard change, I upgraded to Electric Eel.

        I tested that and I get full speeds. Upwards of 40-60mbps compared with the 1mbps I get when downloading to the NFS share

            Yes I’m pretty sure I’ve got it narrowed down to issues with NFS shares from TrueNAS. What I can’t figure out is how to fix it. I may do a backup, reinstall truenas, import backup, and see of that fixes it. I’m thinking potentially its an issue from reusing my old installation with the new motherboard, processor, and corresponding hardware.
