Hyper-V network performance issues with Broadcom drivers

I have seen various issues regarding certain Broadcom drivers, and Hyper-V on HP/ Dell servers.  A ping time between VMs on the same host can be 60-100ms and file copies painfully slow.

The advice is to disable the VMQ features.

Show all network adapters, look for the column “Enabled”

disable-netadaptervmq -name <adaptername>
Disable VMQ for specific network interface

disable-netadaptervmq *
Disable VMQ on all network interfaces
