Hello, I'd like to understand the use-cases to use SMB multichannel. Especially, if the SMB client and Samba server are talking over the WAN. When does one see an improvement in throughput with multichannel? For instance, does copying multiple files result in parallel copying over multiple connections over the same session? Your inputs are appreciated. Thanks, Madhu

Thanks for your response! In other words, would the client be encouraged to open multiple connections with the server to access multiple files in parallel? -Madhu On Saturday, February 18, 2017, Jeremy Allison <jra at samba.org> wrote:> On Fri, Feb 17, 2017 at 09:09:10AM +0530, Madhusudan R via samba wrote: > > Hello, > > > > I'd like to understand the use-cases to use SMB multichannel.
