bottleneck in CHR HELP !!

Hi,

I am presenting a problem, I am installing a new CHR and doing laboratory tests I present the following problem when generating traffic.

The results are the following:

UDP
Send 4.0 to 5.0 Gbps (Maximum)
Receive: 9.0 to 9.8 Gbsps

TCP
Send 9.0 to 9.8 Gbps
Receive: 4.0 to 5.0 Gbps

as they will realize the limitation that is generated is reversed.

Currently the Server is a PowerEdge R640 with intel x710 nic, and we are using 10Gb SFP + DAC cables.
SO Hyper-V

It has P-unlimited trial licenses

And our interfaces are in:

Autonegotiation: Incompleted
Rate: Unknown.
The SMT is disabled.
What can be the cause of this?

I hope I can count on your help, best regards.

did you solve this?
if yes, how did you
