[SOLVED] Fresh Proxmox & pfSense+ install - Slow network speeds

[rtorres]

Hello all,

I'm having a bit of a difficulty with the internet speeds on a fresh install of Proxmox and pfSense.

I was using an HP EliteDesk 805 G6 with an AMD Ryzen 5 processor with had an Intel i225-V 2.5GbE Flex IO V2 NIC for WAN and a Realtek 8156/8156B 2.5GbE USB to Ethernet for LAN. It was working FLAWLESSLY! Getting 1.30Gbps+ with that setup:



I decided to upgrade to an HP Pro Mini 400 G9 with an Intel Core 17-12700T. I used the same Intel i225-V 2.5GbE Flex IO V2 NIC for WAN and Realtek 8156/8156B 2.5GbE USB to Ethernet for LAN but am getting a miserable 200-300Mbps. This is happening without packages installed on pfSense, fresh Proxmox copy as well.

I have tried reinstalling pfSense but same results.

Weirdly, I tried both NICS on another HP Pro Mini 400 G9 with the same i7-12700T processor but with Windows installed and I get 1.30Gbps+ on both NICs. The only difference is Windows is installed rather than Promox.

Does Proxmox treat AMD and Intel differently when it comes to the drivers? I have also noticed that the new HP Pro Mini has the HP Wolf Security - I don't know if that makes a different or not.

Here's more info on my node:

and when I type in lshw -class network on my node:

What are your thoughts?

Thank you for the help!

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

  • You should see your new parameters attached to end of line

just quoting @jan.reges from other post - these parameters helped me to resolve my perf issues.

Warning for ZFS users UEFI ONLY: if you are booting to ZFS disks, updating /etc/default/grub and update-grub will not help.

If you want to add pcie_port_pm=off pcie_aspm.policy=performance to the kernel even when booting on ZFS, you must add these parameters to /etc/kernel/cmdline and then run proxmox-boot-tool refresh. After the reboot, you should already find these parameters by cat /proc/cmdline.
