My AVG copy speeds are
* 11.4MB from NAS to VM
* 14.5MB from VM to NAS
The data is not leaving the box so I don't know why it is so slow. It's a primary reason I bought the 873.
Need more information about your configuration for Qnap, VM, VM OS, etc.

I'm using the same virtual adapter as the NAS itself is using. I decided not to go to a second adapter to limit any potential that traffic would flow to a physical switch.
My hope is that by visualizing an OS on the same box as the SAN, I can maximize throughput for a very intensive CPU & I/O workflow I have.
Advice on how to maximize this would be greatly appreciated.

What is you VM settings in VS? Did you install the latest virtio drivers from the fedora project website?

There is no way to "insert a vm Driver", I can't find a SCSI controller in device manager. Not sure what to do? Could not find an updated procedure in google searches or on the forums.
I'm experiencing the same poor performance on an TVS-882 copying files into a vm.
This is my setup:
TVS-882 i5 16GB
6x 10TB Seagate Ironwolf (Raid 6)
no SSD (so far)
Virtualization Station 3.0
QTS 4.3.3
Virtualization Station:
vSwitch in bridge mode (NIC4 connected)
VM Windows 10 Pro x64 on the same volume as the smb share
4 cores, 4GB RAM
virtio drivers for hdd and lan installed
I can see around 120MB/s transfer speed when copying a 4GB file from within the vm from an smb share to the same smb share on the same volume as the vm. (Also tried with Intel Gbit ethernet driver instead of virtio which gave the same result but showed datatransfer on the physical network.) I would have expected a better performance with the virtio network driver as data is not transfered though the physical network. Seems as if the Raid itself is the limiting factor here. So it's all good.
But: Copying a file from an smb share into the vm is another story. The transfer begins with 100MB and slows down to 3-6MB/s after a couple of seconds. Copying a file inside the vm starts at 25MB/s and slows down to less than 500kB/s!
Will moving the vm onto an SSD help? Will using SSD cache help?
I have a tvs 873 I recently purchased, it has 64GB. Set up windows 10 VM, installed airdc++ and discovered to hash 250gb it would take hours. Speed was 17MB/s. Then I decided to install airdc web ui on the NAS via qpkg, it hashed at 170MB/s. I was not expecting VM network speeds to be this slow. Now I'm thinking of instaliing my bittorrent client on the NAS too.
Update: 5/7/2017
Changed the model of network adapter from default Realtek Fast Ethernet to Intel Gigabet Internet. Now i get speeds of 80 to 100MB/s.
