Network problem in a guest domain cotroller

On a DL360 Gen 8 deployed Microsoft Hyper-V Server 2012 R2. On the Hyper-V server deployed guest domain controller Windows Server 2012 R2. Guest server uses a virtual switch (Microsoft). Response time the guest domain controller is more than 100 mc. By the way, on a another guest server (no DC) on the same host response time less 1 mc.

This problem occurs only DL360 Gen8+Hyper-V Server 2012 R2+DC. For example, on a DL 380 G7 all right.

On all servers updated to SPP 2014.02

The problem can be solved if disabled VMQ (Virtual Machine Queue) on a Virtual Switch.
I think, the problem relates a Bradcom NIC.

Is possible to find a solutin without disable VMQ?
