Hello, I'm running Samba 4.4.5 with enabled SMB Multichannel. The Linux server has two 1GBit/s NICs and for testing purposes I've shared a tmpfs mountpoint with 2GiB and ~2GiB large test-file. My Windows 10 host has one dual-port 1GBit/s NIC, and if both interfaces are enabled, Get-SmbMultichannelConnection lists active multichannel connections to my Linux SMB server. If I disable one NIC on Windows, the other NIC is used with ~1GBit/s when transferring the test-file from Linux to Windows. If I enable both NICs, instead of 2x1Gbit/s I only get ~500MBit/s per interface (but both interfaces are used...

...the client side, I am running another EC2 instance but it is a Windows Server 2019 instance. SMB3 is supported and multichannel support is enabled by default, along with BandwidthThrottling being disabled. When I connect to an SMB share hosted on another Windows EC2 instance, the results of the Get-SmbMultichannelConnection -IncludeNotSelected command returns that the connection is a multichannel connection. However, when connected to an SMB share hosted on my Samba EC2 instance, I get no results for it at all. The results of Get-SmbConnection does return a result showing a connection is established to my Samba ser...

...when enabled? It's been a little more than a year since this question was raised. 1. What is the status of test integration and production readiness for multi channel? 2. I don't see RSS support from Windows Server 2019 clients connected to Samba v4.10 with when I run the PowerShell Get-SmbMultichannelConnection command. I only see SMB multi channel performance improvements with dual NIC on different subnets as noted in this thread: https://marc.info/?l=samba&m=159164098125194&w=2 If this expected behavior? I have the following settings in my config: server multi channel support = yes aio rea...
