Today while doing some network testing with the iperf command I realised the Tinkerboard 2 only seems to get up to 15Mbps when testing UDP.
Not sure what the cause is here, we're running the Debian image, haven't made any major changes, a different computer plugged into the same port gets 500Mbps, any ideas what it might be?
The only thing I could think to check was the link speed on the interface and that Wi-Fi was disabled, both of which are set right.

TCP works fine, up to 800Mbps which is what we expect.
Slow UDP networking speed on Tinkerboard 2

Hi,
Today while doing some network testing with the iperf command I realised the Tinkerboard 2 only seems to get up to 15Mbps when testing UDP.
Not sure what the cause is here, we're running the Debian image, haven't made any major changes, a different computer plugged into the same port gets 500Mbps, any ideas what it might be?
Here's my random windows laptop on the same port:

Any help appreciated thanks.
