On the one hand I am using a Nvidia Jetson Nano together with an Auvidea Carrier Board JNX30B and a 10Gbps network card (ASUS XG-C100C). On the other hand I am using a desktop computer equipped with Intel X550 network card. Both network cards are connected with a standardized ether-net cable of category CAT 7 and are able to transfer data with 10Gbps. Ubuntu 18.04 is running on the Jetson Nano and Windows 10 Home is running on my desktop computer. Additionally, I have the possibility to run Ubuntu 18.04 via an external SSD drive on my desktop computer. I am using iPerf3 for measuring the bandwidth.
What works so far: Once I run Ubuntu 18.04 via the external SSD drive on my desktop computer connected to Jetson Nano I achieve at least 8Gbps. During the measurement I am using Jetson Nano as Sever and the desktop computer as Client: Linux to Linux measured by Iperf3
Now to my problem: When I run Windows 10 Home on my desktop computer using the same Hardware as above I just achieve 660Mbps: Linux to Windows measured by Iperf3
What I've tried so far but didn't solve the problem:
First, I have proofed the Intel drivers on my desktop computer by the driver support assistant. This assistant came to the result that all drivers are up to date.
Second, I checked the settings of both network cards and made sure that the auto negotiation and speed (10Gbps) is set up.
Settings of Asus 10Gbits network card
Settings of IntelX550 network card
Third, I tried to resize the TCP Window size on my windows home system to 85,3kB as described here: https://docs.microsoft.com/de-de/troubleshoot/windows-server/networking/description-tcp-features
Does anybody of you had the same issue or know why Windows reduces the bandwidth anyway? Thank you for your help in advance.
Cheers
Christoph
