I need your help !
I’m working with 3 identical boxes embedding Intel Xeon E5-2650 CPUs and connected with Mellanox MT26428 ConnectX-2 40Gbps cards. Two boxes are running Redhat with OpenFabrics driver whereas the third one is running Windows 10 with the last Mellanox WinOFED drivers (note that i only have the admin privileges on the Windows box).
Running iperf gives me an acceptable bandwidth between the 2 Linux boxes (~19 Gbits/sec) but gives me poor results between Linux and Windows (~1.5 Gbits/sec).
I have tried to tune my Windows settings by following this Windows server tunning guide ( https://community.mellanox.com/s/article/howto-configure-rss-on-connectx-3-pro-for-windows-2012-server ) but i didn’t get significant progress.
Do you have any idea concerning this performance issue ?
Due to those IPoIB poor performance between Linux and Windows, i’m considering using RSockets API. Are they supported with Mellanox WinOFED ?
Thank you !
