Hello,
Not 100% sure this is the best place to post this but figured I would give it a go.
Situation.
User has a Lenovo desktop running windows 7 and has a shortcut on his desktop pointed to a share folder located in our DC. We have a 50 meg connection between user's site and DC. It's also only about a mile down the road so there's little latency. When users copies a folder within this shortcut it takes 10-15 seconds 11 meg folder and Wireshark has confirmed that the culprit is SMB2 according to time delta.
I have checked his pc, port, cable and phone and nothing seems out of order and when I run the same test on my laptop to the same file share it only takes my 2 seconds to copy and paste something that's 11 meg compared to his 10-15. I have windows 10 and have tried messing around with his TCP settings on the local NIC. It may be just a straight up limitation on his NIC as to why it takes so much longer than my pc but I would like to prove this. Maybe, SMB2 is somehow handled differently in a windows 10 machine vs 7 but I don't think that's the case.
any help would be appreciated.
Thanks,

Windows 10 uses a newer version of SMB (version 3.1.1) if both endpoints support it.
However, unless your DC is 2012 or newer, it won't support SMB 3.x anyway.

Hello,
Thanks for the quick response. When I ran WS on my windows 10 it shows SMB 2 so I don't think that's the case. The server in our DC is a 2012.
