- Network - 3 locations, Server 2012R2 with 8-10 file shares per server (same shares replicated amongst 3 servers using DFS).
- plenty of resources on servers - 1 virtual, the other 2 physical
- Approx 1.3 TB with literally thousands upon thousands of folders within shares.
- 90% of client machines are Mac running OS X El Capitan or Sierra
- symptoms below are reported often but not all the time, occur regardless of location or time of day, regardless of which Mac used
- symptoms below do not occur on Windows laptops in same environment


Problems reported:
- slow on the Connect to server (SMB share) to get username/password prompt
- slow to authenticate once username/password entered
- once authenticated, slow to list contents of directories with many files/folders

(bandwidth to server tested ok during these issues)

Actions taken over the last month:
- re-enabled SMB 2/3, disabled SMB 1 (SMB 2/3 disabled early in 2014 on initial deployment due to other issues)
- added Smb2CreditsMin (set to 768) and Smb2CreditsMax (set to 16384) to registry on "main" server for testing
- bound Mac to AD

Have tested this in another, much smaller Windows network with exact same issues.

Nothing tried above has made marked improvement.

Open to suggestions.

We have the same issue.  In our tests if we unbind the mac from AD the performance is greatly increased.  We are currently thinking it has to do with the authentication being used between AD and OSX through the SMB protocol.  We are working with Microsoft support they have the same theory as we do for the moment.
