    Should it take 10 hours to export 32GBs of VMs in XenServer?

      You can try exporting directly from XenServer but I believe you can only export in XVA format when done in CLI.

        I just don't know why the backup that is 8GB was done in a number of minutes but the one that is 17GB took 9 hours. That's like an exponential increase!

        I plan on upgrading XS which is why I'm exporting the VMs in the first place. I hope the new file system layout of XS helps fix this.

          You know, I haven't really looked back into it, but I noticed that my servers just don't have the proper speed at all in XS.

          I wonder if it is some sort of network driver issue.

          Have any of you ever tested throughput on your XS VMs? I haven't had a chance to do it, but it might be interesting.

            @BRRABill I've run a number of iperf tests, and get the 850 to 920 mbps I'd expect from a gigabit network. There is something really wrong with exports in XenServer 6.X

              Yeah I just never circled back around to it.

              I have to put that on my to-do list.

                I get great bandwidth for all XS ops except import/export. Migrating vms/storage is almost always 100+MBps

                  The import / export functionality is supposed to be greatly improved in XS 7.1.

                    10 hours for 32gb . . . . seems excessive even for the poorer performance of 6.5.

                          Likely story.
