[proxmox]

post #3 I state that I'm using proxmox also I noted the NIC hardware I was using which is all intel, i266V and X553. No realtek. It has 8GBs of RAM. All suggested tunables were configured on this more than a year ago. This is system has run very well for around 2+ years and I kept it up to date weekly.

Please note I'm now fully on X553 NICs for WAN and LAN. They are shared to the VM via passthrough on proxmox (host). It is still slow for incoming bandwidth... upload looks to be back to normal. ( ~300 Mbps Down ( this should be 2000 Mbps) , ~280 Mbps up). I changed nothing on the device all last year except the firmware and only some where in the 4th quarter of 2025 did it drop off a cliff.

So this is Proxmox... Can it handle the hardware offloading, or is this turned off? If you have it off, can you turn it on. Or the other way around depending on the circumstances.

The NICs are given to opensense with PCI passthrough raw.

so after updating the firmware I didn't see any difference in the speed. So I got a SFP+ 2.5/5/10 module and just made the change over to the that as the WAN as I had a couple spare SFP+ X553 . That also didn't change the speed. So I've run out of ideas. I'll see if I can get into the modems admin interface and see if I can see anything.

Light work day and spent it going down a rabbit hole

got iperf working, I tested the LAN side that has a 10GB SFP+ X553 DAC into my switch. Looks like I'm getting full bandwidth there. So started to really look hard at the I226-V which connects directly to the modem. After looking the interface:

started to think I needed to look at the threads on the forum about i-226V

I was running NVM version 2.14 ... so I'm updating to 2.32 tonight. successfully updated a couple of the spare NICs already. but not seeing a speed improvement when move my WAN port over to an updated one... though I might be getting them mixed up between the proxmox and opensense. I have failover WAN port that I also use and maintenance por.

I'm trying to test the LAN side with iperf and I'm not sure what I'm doing wrong here but I can't connect to the client on on opensense, firewall rule is in place to allow any lan source to talk to the firewall on any port

This is what I have for history. In December I got really busy with work and it's only now started to cool off and I can start to look at some issues.

Yes this is on a comcast DOCSIS line.

The system is an Intel Atom C3758R with intel i226V .  Opensense is running as a VM in proxmox currently by itself.

The throughput has drastically changed. I tested directly on the modem with a laptop and I'm able to get around 800Mbps D / 300 Mbps U using fast.com or speedtest.net . Yes this is not the speed I use to get but the upload is really what I rely on. The throughput of opensense has taken a dive and I'm not even sure where to begin.

So my WAN down and up started to tank sometime in december and all I can think is an update caused it. Today I had some time and tweaked the MTU a little with middling to no change:
