I got my first 10 gigabit client device, I’ve been able to get reasonable speeds out of it but I’m wondering if a) iperf3 is not the best test for this and b) whether and how to set something like jumbo frames on both sides without causing issues with the br-lan device.
Note that I’m able to max out my 2.5 gig clients (through a Mikrotik SFP+ switch) but I’ve only got one 10 gig device I can test with at the moment.
