Running iperf tool client/server between windows7 and linux. In Linux UDP buffer size set to maximum using cmd "sysctl -w net.core.rmem_max=8388608"(rmem/wmem) and trying to push 1Gb of data successfully. How to increase or set to max UDP buffer size in windows machine? What are the registry keys/values need to add?

From here: Change default socket buffer size under Windows
[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet\Services\Afd\Parameters]
DefaultReceiveWindow = 10240
DefaultSendWindow = 10240
Thanks, Tim.

Hi Balu, were they the values you were looking for? Or are you looking for different values? – Tim Haintz Nov 16 '16 at 10:25

That answer deals with TCP, not UDP. – Jannes Jan 11 '17 at 13:17
