I hate VMQ

Alright. If you are going to push a technology, why don't you try and make sure it works before enabling it by default.
@Microsoft said:
VMQ is a scaling networking technology for the Hyper-V switch. Without VMQ the networking performance of the Hyper-V switch bound to this network adapter may be reduced.
What they don't say clearly is that VMQ is something Intel baked up in 2010. They also do not tell you that your Hyper-V server will perform like shit if it is enabled and the card does not support it.
Today's lesson is VMQ and Broadcom chips. The two do not mix.
Think you can guess when it applied?

Yeap took nearly 3hrs when I deployed Hyper-V to figure that was the cause of our poor performance between VM's

I disabled it on the VM but it did not resolve the problems. In the past, that is all I have ever needed to do.

Think I had to disable on the Hyper-V Level via powershell on the NICs

I think this is the command to disable it system wide.

I simply disable VMQ to start with. I don't care what brand NIC is in the system. I have seen it cause no end of grief for folks online, so I default to turning it off.

I thought QLogic released new drivers that "fix" the VMQ issues?

QLogic = Broadcom = Disabled VMQ, lol.
Edit: I have two systems here with the QLogic Drivers, and they did not help at all.

@dafyre I know on one of my Dell machines I did a new driver that seemed to fix the vmq performance issue; on the other I did just completely shut it off.

I'd be less hesitant to leave it enabled if I could trust it to not cause problems.
