WDS on a virtual machine is very slow

WDS on a virtual machine is very slow.  We recently moved WDS to a virtual machine (Windows Server 2016) in Hyper-V.  We also moved it to a virtual machine that does not contain a DHCP server.  We changed DHCP to point to the new WDS server (option 66 or 67).  The deployment process went from taking 45 minutes to 10 hours.  We dove deep into Google looking for a solution.  Changing the TFTP block size did nothing.  All the other VM's seem to be running fine.  Any ideas?

What is the underlying storage ?

What is the specification of the VM ?

We use WDS on virtual machine, to deploy to hundreds daily, with no issues.
