This is an interesting post. How would you go about upgrading the drivers (for i226-v) using the .bin file?

Thanks Brandywine, I'm interested to try these as I'm running an N150 box myself but could you please provide a little more context on what they do?

Thank you!

I have been doing a little digging and the answer has just come to me:

I moved my WAN connection to another port on the box now that I'm running bare metal. Because this is now a new MAC address, I had to reset to reset my virgin media hub (modem), which issued me with a new DHCP public address, but crucially through a different gateway, hence the change in ping response times.

Hi all,

I am running Opnsense 25.7 on an Intel N150, 4 x i226-v (16gb DDR5) topton mini pc. Until yesterday I was running Opnsense in a VM under Proxmox with 3 x cores allocated and 8gb RAM. I have since decided to install Opnsense bare metal on the same hardware.

I have a BQM (broadband quality monitor) running and since the switch my maximum (WAN) ping has been consistently higher - is this coincidence or has anyone seen anything like this before?

I am on Virgin Media in the UK (1140/110 - DOCSIS 3.1).

I have attached the graphs covering 27-07-25 to today 29-07-25 to highlight better what I mean. The red bars are when I made the switch.

Thanks meyergru, I just looked into applying this manually but couldn't see temperature.sh within /usr/local/opnsense/scripts/system.

It's not a huge problem just annoying to see up to 20% CPU usage across 3 x cores (n150) for such a task every 5 seconds. Although, as you say I guess this sysctl call is only made when using the dashboard?

What else is it used for other than CPU temps/ usage?

Thank you meyergru. I did try searching and couldn't find anything that replicated my issue, however your second link looks promising - I will look into it.

I can't get CPU temps as I am running on Proxmox but it looks as though the CPU method mentioned also collects usage data?

It looks as though our hardware is very similar, have you experienced this issue yourself? Or is the patch you looked at making a result of that?

Thanks again, appreciate your help

Good morning all,

I am experiencing what looks to be a spike in CPU usage every 5 seconds (shown in the dashboard widget) when on the web GUI.

It looks like it is comprised of 5-6% system usage, 10-14% user usage, and 0% interrupt usage, and is extremely regular in occurrence - happening every 5-6 seconds. It must also be noted that there is minimum traffic at this point.

I have 3 VLANs configured - a management, IoT, and primary VLAN. I have Wireguard setup, but I am not actively using a tunnel at this point. I have approx. 5 aliases setup.

I am not logging anything from the firewall rules I have set, and am not using Netflow or any IDS/IPS.

My WAN is DHCP (not PPPoe, etc.) 1000/105.

I am running Opnsense 25.1.11-amd64 in a Proxmox VM, on a little N150 box with 4 x Intel i226-v NICs. The VM is allocated 3 x 'host' type cores, with NIC passthrough of 2 x NICs and 8Gb of memory. I am using CRC offloading, TSO offloading and VLAN hardware filtering. Proxmox is up to date and other than this performance seems fine.

I am not using traffic shaping.

I have tried using top and catching these spikes by monitoring the shell but I'm struggling to. It appears as though they are a php-cgi process and/or a python3.11 process. However, when I press 'c', it won't let me view the full path of the process.
