Hi, my windows pc has AQC107 10g nic which is directly connected to my unraid server with a X550-t2 nic. When I was on 6.10 RC1, I can enable SMB Multichannel between the two machine by adding lines to smb-extra.conf: #unassigned_devices_start #Unassigned devices share includes include = /tmp/unassigned.devices/smb-settings.conf #unassigned_devices_end server multi channel support = yes aio read size = 1 aio write size = 1 interfaces = "10.120.0.2;capability=RSS,speed=10000000000" On RC1 with SMB Multichannel enabled, I can hit 600-800MB/s transfer speed to user share folder. However after upgraded to RC2, transfer speed dropped to 200-300MB/s. I checked on Windows side with Get-SmbMultichannelConnection conmand and it shows RSS Capable is false (which was true on RC1). Server Name Selected Client IP Server IP Client Interface Index Server Interface Index Client RSS Capable Client RDMA Capable ----------- -------- --------- --------- ---------------------- ---------------------- ------------------ ------------------- 10.120.0.2 True 10.120.0.1 10.120.0.2 12 13 False False I know RC2 is the version that start to support SMB Multichannel, but it seems worse than RC1 in my setup?Does someone have same issue or maybe I have incorrect settings? I also tried removing those extras lines from smb-extra.conf it dosen't work neither.
