Have an old Cisco UCS C220 M3 with a fiber 10G card in it. Proxmox is installed and the bridge is showing 10G properly.

Linux VM, Pop_OS!, using the bridge as it's NIC. Seems to only be showing at 1G link speed though.

I have a QNAP NAS that has a 10G fiber NIC as well. Using a Cisco 3650X that has a 10G modular card in it. Host, NAS are all connected by fiber. My LAN transfer speeds are horrible, heck they are even horrible if I only had 1G.

Transferring a folder of .mkv files for a TV Series from the VM to my plex folder on the NAS. I usually do this by way of uploading via the web interface as it helps with permissions. So, I know I'll lose a bit of speed, but this is what I am getting. I mean, this is crazy slow and I dont know why. Been this way for awhile. Finally just had the time to post about it.

Using VirtIO (Paravirtualized)

Any suggestions? 66GB is taking like an hour which is kinda crazy.
 
Is that not the VirtoIO (Para virtualized) that I sent the screenshot of? Or are you asking about something else?
