After dabbling with Alpine and going back into the bios I realised that PCIe 1 and 2 were set to Gen1 (I did think I had changed them to Auto a number of years ago). After amending to both to Auto I'm now getting 2.10 Gbits/sec to a public server from OPNsense, 2.12 Gbits/sec from Win11, and 2.35 Gbits/sec OPNsense to Unraid. Thanks for all the input.

iperf3 was done with -P 4

I'll get a Linux based Live Boot up over the next few days and give it a test, plus maybe a fresh OPNsense basic install on a spare drive.

Peaks at about 40%.

iperf3:
1.48 Gbits/sec from the router to a public server.
1.28 Gbits/sec from Win11 to the same public server.
1.60 Gbits/sec from Win11 to OPNsense iperf3 server.
2.37 Gbits/sec from Win11 to Unraid (N95) iperf3 server.

I've just upgraded from a PPPoE based 900 / 110 full fibre contract to a DHCP based 2000 / 2000 with YouFibre.

I get 2000 / 2000 with the supplied router using Windows 11 and Ookla speedtest.

I get 1400 / 1400 with my N100 i226 based router both from bare metal OPNsense cli and Windows 11 (direct connection to the router).

I get similar 1400 / 1400 iperf3 numbers to and from Win11 to OPNsense (and over 2000 both ways to Unraid on the network)

I was hoping that my router would run at full 2000 / 2000 speed. Am I being unrealistic?

The release notes for 25.7.4 details:

o interfaces: replace MAC vendor database from py-netaddr with a simple local implementation

Is there a mechanism to manually update the MAC vendor database or is it updated periodically / automatically?

The patch resolves the problem for me. Thanks

net.inet6.ip6.dad_count = 10 made no difference.

I tried up to 60 with no positive result  :(

OK I'll try that a little later tonight and let you know the outcome.

I've sent the log via private message

Sorry 23.7

2.19_2

After every reboot I need to restart radvd in order to get an IPv6 address on my windows machine.
