Virtual Network Queuing causes poor performance on Dell servers

In troubleshooting some poor network card behavior on my Dell PowerEdge T420 running Windows Server 2012 with three virtual machines on it, I came across these articles that describe problems with virtual network queues enabled on Broadcom NICs.

I upgraded to the latest drivers and disabled the virtual machine queues.  My sample size was small and problems intermittent, so it's hard to say if I resolved the issues, but it's worth noting.
