After removing the dedup feature, there was something (cant remember off the top of my head) that you should do to the volume , optimization related.

When you try to transfer files to the VM, the transfer just randomly pauses and un-pauses after a few hundred megabytes of each burst. The pauses last around 15 seconds but can be a minute or more. It’s worse the bigger the file is. 2012 R2 server fully patched with 2 CPU & 5GB of RAM & 60GB system & 800GB storage on VMware backed by a SAN. · File transfer dialog on Windows 8 usually bottoms out at 0 bytes/s when this happens. Pausing or cancelling transfer on client doesn’t register until it un-locks. · Resource Monitor on server shows Disk as no activity when this happens except for maybe some random bursts · Happens with robocopy and xcopy as well as native Windows Explorer · Happens connecting from both 2008R2 and Win8.1 with different network paths. · Occurs when transferring to system drive or data storage drive. · NTFS/REFS doesn’t matter on storage drive · SMB signing is off · Absolutely nothing installed on the server. NOTHING. No roles. No extra features other than the GUI. · Pauses are worse the bigger the file is. · Data Deduplication and File Resource Monitor used to be installed, but they’ve been removed for troubleshooting. · Tried uninstalling SMB 1.0 on server Again, ANY ideas or tips appreciated.
