      So posting here on behalf of an SW user (topic here) who's getting horrid throughput when he has two nics bonded on his HyperV 2012 server.

      Any ideas?

          I'm not certain, just posting here to try and get more eyes on his issue.

          The throughput jumps as soon as the nics unbonded.

            Disable VMQ on the NIC devices if that option is available.

              This is the biggest thing I have found.

              VMQ is enabled by default and likely his hardware does not support it.

                I've gotten to where I disabled VMQ and *Offload on any network card that is in my system these days... Especially if I am going to use Hyper-V... 99% of the times I've seen either (or both) used, it has caused some really awful performance!

                    I doubt that they would notice, but it's possible.

                        Not sure I've ever heard of someone trying it. Maybe just do it during lunch? What kind of workload(s) is it?

                              DC will definitely be fine.

                                  It has been over a year since I did this on a running system. I do not recall any big issue.

                                  Performance was so crappy though that even a quick blip would have just be ignored.

                                    I like Scott's idea, warn the management at least that you are doing it, and do it over lunch if they approve, otherwise schedule for tonight.
