I've setup SMB Multichannel on my Truenas (intel I210 and intel I219-LM onboard) and transfer from my windows desktop to the NAS is utilizing multichannel. However, when I transfer from Truenas to Windows, I only get 1Gbp/s speed.
My desktop also has the same two NIC's onboard (I210 and I219-LM). I've double-checked the drivers (installed the latest from Intel as well) and RSS is enabled for both NICs. But when I checked Get-SmbClientNetworkInterface it shows that the I219-LM is not capable of RSS.
At least I know why transfers from Truenas to Windows is not utilizing multichannel, but I can't seem to enable RSS on the I219-LM.
I forgot to mention that the I219-LM NIC on the Windows machine is running on an Asus WS X299 Sage motherboard. The Truenas is running on an ASRock C236 WSI.
So far I've only been able to find a similar topic with RSS problems on an I217-LM. https://community.intel.com/t5/Ethernet-Products/I217-LM-no-RSS-possible-under-Win-8-1-Pro-x64-driver-setting/td-p/488447
