Hello,
I just testing Proxmox VE on my environment. I attached 1 network cable on the first port of my PowerEdge R730, the other end is connected to mikrotic if that matter, as I already know my infrastructure is running on 1GBs to other VMs and Hosts in general. While I transfer some files in a VM on proxmox I come across speeds of 100MBs speed network.

After some investigation I found that even if the Linux Bridge is negotiating at 1000MBs for both the host and VM I have the following iperf3 results.

Some Info of Proxmox installation
$pveversion pve-manager/7.1-7/df5740ad (running kernel: 5.13.19-2-pve)

uname -a Linux iphis 5.13.19-2-pve #1 SMP PVE 5.13.19-4 (Mon, 29 Nov 2021 12:10:09 +0100) x86_64 GNU/Linux

Anything will help because I want to move to proxmox and something like this it will be a huge problem.
