Quote from: nero355 on June 07, 2026, 11:29:15 PMOfcourse you will always have to measure with as much threads as possible and sometimes even raise the window size and stuff like that... :)

Any suggestions what to look for or which logs might be helpful?

Quote from: ou1 on June 07, 2026, 07:45:29 PMRegarding TDP - yes, this CPU can use a lot more power. I got it up to 40W by running iperf3 directly from the firewall, but otherwise it idles at 18W, which I can live with. Maybe there is room for optimization, I haven't done anything yet.Sometimes it's better to have a slightly higher TDP rated CPU that is good at "Racing back to IDLE" instead of having a low TDP rated CPU that needs a lot more time for the same task and because of that eventually consumes more power for the same task.

Quote from: meyergru on June 07, 2026, 06:51:47 PM1. There is a big difference between OpnSense routing sessions between different partners and OpnSense being the endpoint (the latter one is slower).So you are saying that when I measure iPerf3 speeds between OPNsense and a Client that the speed will always be lower than between two any other type of Clients on the same subnet ?!
Quote2. Since this is iperf, I also like to point out this article, point 10. I totally depends on how many TCP sessions you use.Ofcourse you will always have to measure with as much threads as possible and sometimes even raise the window size and stuff like that... :)
Pulling these together, I see ~1.87 Gbps with iperf -P1 vs. 3.56 Gbps with iperf -P4 vs. 6 Gbps when OpnSense routes only.
