For your information i've connect the two PC together with the DAC.
On win 7, you had to enter the number of MTU and on windows 10 it only giving you two choise, 1500 or 9000.
With win 7 set to 9000 or 9014, i get even lower speed 1-2 mb/s...
Changing the send and receive buffers???
You mean the(winsock default send- and receive-buffer size) by changing the registry?
It only test machine, i've disable essential/defender...
I will test tomorow two same machine.
I'm using different driver on both... Windows 7-10. I will install two physical machine to test with the same driver.Hi I had similar performances. Now I am getting quite steady 9Gb/s +speeds with Iperf 3. I have cheap dac's and same nics as u have. I have several windows 10 machines and one linux fileserver. No virtualization.
My checklist for speed is :
-On windows machines the drivers
-mtu I have 9014 on win machines, 9000 on linux, maxed out on switch
-windows driver... max out send and receive buffers to 4096 or something like that
-turn off antivirus. For me this affected suprisingly much to the iperf test speeds.
(Somepeople did recommend turning off the windows firewall aswell... I didn't)
