Hi all,

I have a SANLIN3-T1 NBaseT adapter. I tried to perform 10G/bps throughput test, using iperf3 between Linux and windows. A SANLINK3 is connected windows but windows showed only 6.5Gbps. 

Is there any recommended configuration for reaching 10Gbps throughput in Windows?

10GB is your bandwidth, why would you like to make full use of it? The graphic in resource monitor cannot present that your network speed is not satisfied 10GB bandwidth.


Looks like it's only compatible with 6.5Gbps

Hi Hyok, 

Please make sure you connect SANLink 3 to a windows which has the inbuild Thunderbolt 3 port and please avoid any adapter/converter in the setup also if you have a  switch in the setup then please try to enable Jumbo frames and try using any speed benchmark tool like BlackMagic to check the speed.
