Slow copy performance in Virtual Machine (VM) Server 2012

I had an issue with very slow copy performance when trying to copy from a server to a virtual machine when the virtual machine is running on Server 2012 Hyper-V.

It seems there is an issue with Broadcom NICs to resolve the issue edit the physical nic in question and disable the option called “VirtualMachineQueue”

This resolved it for me.
