Environment:
Dell T30
Onboard Intel 219-LM NIC
E3 1225 V5
16gb RAM
500gb Crucial MX500 for host OS
1tb Samsung 860 EVO for single VM
Running Server 2019 Essentials with no additional roles than Hyper-V. Single VM running 2019 Essentials. Allocated 2 vCPUs (tried it with 4, no difference), 10gb of RAM, and a 127gb C drive and 750gb E drive. Both are located on the 860 EVO.
Problem: In the VM, when copying files around, everything is speedy gonzales with no problems at all. If I try accessing those files over the network from another machine, performance drops off a cliff and files copy at approximately 1MB/s max.
What I've tested:
I'm at a loss here as to why the performance is so awful over anything related to networking! Any ideas of what I may have missed or can try?

What I've tested:
- Ensured network was connecting at Gigabit.
- Turned off VM Queues
- Tried a new virtual switch with a USB gigabit nic.
- Tried mapping a drive locally on the VM itself and copying files. It performs super poorly here just like it did when trying to access a file from an external workstation.
- Tried mapping a drive to the loopback adapter \\localhost\data\crap and copying files. This gives the same behavior where file copies are excruciatingly slow.
