Hello,
I have recently noticed that two of the three built in NICs on my W680 motherboard appear to be limited to a 50Mbps download speed. These are the only ports that I have set up and use virtually (vmbr0 and vmbr1). All of the onboard NICs are I-225. I have not confirmed version, but the W680 chipset is pretty new and I would think they are the later revision of the I-225. I do have an x550 card that gets passed through to my NAS, but there are no issues there.
Speed was tested with speedtest-cli, iperf3, and with some downloads. It happens only on the actual internet speed tests and downloads. Iperf3 on the LAN is a full 2.5Gbps. This happens on the host and on a few VMs. I do have at least one Ubuntu Server VM and within it a Docker container that gets full 1Gb up/down, which is what I have from my ISP. The slow download happened in a Windows Server VM during a Steam download and on the Speedtest website, but just after a reboot of the Windows VM, I got a fast game download (with some speed loss due to VM overhead). Proxmox was still at or under 50Mbps in between the fast downloads in the Windows VM.
All of my VMs are using the VirtIO NIC model and I mounted and installed the drivers for it in the Windows VM. The Proxmox management side is on it's own port and the VMs share the second port. Most tests were done on the host with VMs off or only 1 or 2 running.
For what it is worth I have tried a couple different kernels and I am pretty sure I had full download speeds at one point, at least when pulling images from URL in the Proxmox GUI, but I guess I can't be sure.
Does anyone have any ideas about what is going on? Is this just crap I-225s? I've had a few add-in I-225s that worked fine on my previous Proxmox build.
