[SOLVED] Slow Internet speeds new Proxmox + Pfsense install

Networking & Firewalls

Hello there!

I just changed my HP EliteDesk 805 G6 AMD Ryzen 5 for a HP Pro Mini Intel Core i7 and am experiencing VERY slow internet speeds.

I have a 2.5GbE Intel i225-V FlexIO NIC card as my WAN and a Realtek 2.5Gbe USB Ethernet adapter as my LAN.

I was getting 1.38Gbps Internet speeds when I was using the same FlexIO NIC and Realtek USB to ethernet adapter on the HP EliteDesk (AMD) but since I moved over to the HP Pro Mini the internet has been capped at 210-230Mbps.

Pretty disappointed as the HP Pro Mini is suppose to be newer and better than the older HP EliteDesk I had… I even moved over my pfSense + license over to the new unit!

Not too sure what I can post to better assist. :frowning:

This is a fresh install of proxmox and a fresh pfsense plus (latest) install. Same results with and without packages installed (pfblockerNG, WireGuard, etc), wired and wireless.

Could it be a driver issue or some kind of setting that needs to be ticked for newer 12th gen Processors? I already have hardware offloading disabled in pfsense…

I’m completely at a loss.

Thank you for the help!

Any time pfsense is used as a VM the potential issues and weirdness goes up. It’s not recommended to virtualize pfsense, but you could check you installation from their documentation on how it should be set up.

You said you disabled hardware offload in pfsense, but usually you do it on the hypervisor itself, unless that is what you meant. I have not done it on proxmox but on xcp-ng it was just a few commands. It has been rock solid for me on xcp-ng and even MS Hyper-V. So I’m sure you can make it work.

Thank you all for your replies!

I tested the HP 2.5GbE Ethernet FlexIO card into another HP Pro Mini 400 G9 with same processor and Windows 11 installed and get the 1.20Gbps+ speeds on fast.com and speedtest. If I plug in my Realtek 2.5GbE USB ethernet adapter, I get the same 1.20Gbps+ on the speed tests.

As soon as I plug everything back into my Proxmox/PfSense HP Pro mini, I get the same 220-300Mbps no matter if connected directly or wireless.

Would it be something in the BIOS that I would need to disable? Maybe intel proxmox installs handle Ethernet adapters differently?

This unit comes with a built in HP Wolf Security, maybe that might be another reason?

TIA

I FOUND A SOLUTION!

This is what I did to get both of my NICs to get the speeds I was getting:

  • Edit /etc/default/grub
  • Add pcie_port_pm=off pcie_aspm.policy=performance to GRUB_CMDLINE_LINUX_DEFAULT
  • Double check file - cat /etc/defualt/grub
  • Run sudo update-grub
  • Reboot (Important!)
  • Check params from boot cat /proc/cmdline
