How to achieve 10G speeds?

Run your test to something on the Internet.
My internet link is 100/50 so I assume this wouldn't tell me much.

Try to test to something other than pfSense directly. Some other local host connected at 10G would be best.
I have another port of my T540-CR connected to a Proxmox Host so I run a connection from my Proxmox Host to pfSense and this time with the following results:
[SUM] 0.00-10.00 sec 10.7 GBytes 9.22 Gbits/sec 0 sender
[SUM] 0.00-10.00 sec 10.7 GBytes 9.21 Gbits/sec receiverIt seems that my local PC is unable to get 10g speeds even when connection shows 10G.
I apologize since this is not a pfSense related issue.
kind regards and thanks for the prompt support.

That's why I asked if the hardware is up to it. As I mentioned, 10G is a lot and I've only seen it in data centers over fibre. In fact, in between speeds, such as 2.5 and 5 Gb have been introduced, as 10 was too much of a jump.

I’m not convinced it’s a computer power problem as when I run iperf I get only 15% CPU utilization. It’s a 32Gb i7. O would bet it’s something related to network connection or setup as I’m doing a Thunderbolt 3 to sfp+ fiber from PC (Intel NUC) to pfsense. I updated to latest firmware but still no good.
Problem is I have no idea how to troubleshoot it.
Kind regards

Well, you apparently have a computer that can handle 10G. Try iperf against it from that Windows box and see how the performance is. You've already ruled out issues with pfsense and it's hardware.

Yes, me too. 126Mbps over a 10G link is something fundamentally mismatched.
Can you swap the NIC in the TB adapter for a 1G device and test that?Steve

Changed both sides to 1G. Sames results:
[SUM] 0.00-10.01 sec 148 MBytes 124 Mbits/sec sender
[SUM] 0.00-10.01 sec 146 MBytes 123 Mbits/sec receiver -
Still over the same hardware though?
I'm not sure what sort of TB adapter you have. Like an external PCIe cage or a dedicated adapter NIC.I assume the NUC itself has a 1G NIC and that can get ~940Mbps?

Same hardware: from Intel NUC6i7KYK i7 6770hq to pfSense Xeon E5-2686 v4
I'm not sure what sort of TB adapter you have. Like an external PCIe cage or a dedicated adapter NIC.
It's a dedicated Thunderbolt to SFP+ adapter: QNAP T310G1S

You're right. NUC has a 1G NIC too. If I connect to pfSense from this NIC I also get same results:
[SUM] 0.00-10.00 sec 170 MBytes 142 Mbits/sec sender
[SUM] 0.00-10.00 sec 167 MBytes 140 Mbits/sec receiverIt seems problem is not with TB adapter as 1G NIC is also capped at <140Mbits/sec. Maybe a WIN10 config or hardware issue.
kind regards

Hmm, well that's good news, it implies the TB 10G adapter is not the cause so probably can be made to work. Unless you have some traffic shaping set in pfSense it's hard to see what might cause that. Something in Windows guess though I'm not sure what.
