      I'll probably wait till everyone leaves and come in the morning early to double-check the BIOS. The disabling of the VMQ however, when I ran the command it didn't return that I had anything enabled....

      I checked the Xen nic, and it doesn't have a listing in the advanced tab for the VMQ

        I figured it wouldn't, but I was putting it out there anyway.

        If you look at the NIC status, what does it show the connected speed?

          @krisleslie no one has mentioned it, but are you sure that you have GigE end to end? 10MB/s is the speed cap when you have a 100Mb/s network link somewhere.

            You could also have a bad switch in the mix.... that was the case for someone around here recently.

                @scottalanmiller can't be it, because sometimes I see it do 60 Mbps + like during OS install or if I happen to catch it.

                  Potential bad switch as in maybe one of the interfaces is bad? I think a long time ago me and scott thought about switching to 10 gb interconnects for each switch

                    Can't be the NIC (???) I'm doing like a file transfer from one folder to another on the same disk/vm of the vm that I'm running. When I tried last night to copy vm to vm yea after 10 hours only 1/3rd got done give or take an hour or so.

                      OK that takes the switch out of the situation.

                        In the VM or at the Host?

                          As I'm running Crystal Disk Mark the speeds are so horrible I want to vomit.

                                On that note, I'm going to the nearest bottle.

                                  60Mb/s is a fraction of 10MB/s, though.

                                    Drives having SMART issues, maybe?

                                          Nothing has raised a flag to that being an issue. Speeds like that have been present for literally every server I've used over the years with virtualization. I have a fresh new server sitting behind me that when I finish installing XCP to it tonight I bet barely yields much of anything better ;(

                                            I use to believe heh maybe there is a driver issue or OEMU but I've not seen anything like that.
