There are a ton of posts in my profile of attempts to solve the issue with help from here :https://community.meraki.com/t5/user/viewprofilepage/user-id/102579 e.g. this post but the end result was that after literal days of testing with iperf etc I could not get any files to copy form the Hub to the Spoke any faster than ~5mbps despite fiber connections and full-speed 1Gb + speed test results. I spent an entire afternoon on the phone with ATT support (whom we are leasing Meraki from) who got Meraki support on the phone (up through several tiers) and we connected/disconnected/tested for HOURS. If you search google for "SD-Wan slow SMB" you will get a million results. Among those is something "official" the Meraki rep referenced that said that it was a protocol issue with SMB/SD-Wan and the the performance I was seeing was "expected behavior". Believe me, I wish I was wrong but I could not find a solution after months of trying. Stuff like http/s, dns, etc. all work and perform fine over the SD-Wan connection, but SMB file copy speeds are abysmal (our users use software on their machines that load files from the server at the Hub and the speeds are so slow the applications because unusable). As a temporary workaround, I had to create a remote desktop session host, install the software on there, and have the users do their work that way. Going that route, performance was fine. But trying to copy a file from hub to spoke (just standard windows explorer right-click copy/paste) you could see the files just creeping along never more than 5MB/s but typically floats back and forth between 1.0MB/s and 3.5MB/s. Still doing it to this day (just checked; 2 +hours for a 1Gig file). Have you tried contacting a similar type of service offering similar services? Let them know your issue, and ask them if they can sort your problem. It's the only possible way as they have the knowledge of the space you're operating in.
