10GBE and TcpWindowSize with Windows 10

I'm finally upgrading my main workstation to Windows 10, and I'm using Intel 550 10GBE cards for a direct connection.

 

Using iperf, I get only about 4Gb/sec ... but if I set the TcpWindowSize size large enough (iperf switch "-w 2048k") I get the expected 9.9 Gb/sec.

 

This is on a clean win10 install, and it doesn't matter whether I use unRAID as the iperf client or server.... meaning it doesn't matter which system gets the -w flag to initiate the larger TCP window size.

 

Anyone see this before?
