Ok, upgrading to the latest version worked. Thank you.
I see some improvements in the backup speed like:
both are up from about 4 MiB/s
However, i am also seeing vast improvements when backing up from XCP 8.0.0 with transfer speeds (as reported by iptraf-ng) going up to 700 Mbps, which was not happening before.

Hi all,
i'm faced with the same issue:
TestVM (redfour)

where the backup volume is served on iscsi by a machine having raid5 over 1 Gbps back to back connection to the hypervisor.
Mouting that volume in the hypervisor and doing some transfers, traffic easily goes up and beyond 800 Mbps whereas the backups takes forever to execute.
I am uzing zstd as compression and xcp-ng 8.0 on the hypervisor
One thing i noticed is that xo-server takes 100-130% cpu when the backup is executing.
The vm above is about 2gb uncompressed, however larger VMs take over 8 hours to complete a normal backup, nothing fancy.
Thanks,
Viorel

Will update right away to the latest version and test.
Thanks
Hi All,
after re-creating the backup task, i get the following message in the failed task:
RevDNS (redthree)
Snapshot
Start: Feb 7, 2020, 12:00:00 AM
End: Feb 7, 2020, 12:00:00 AM

End: Feb 7, 2020, 12:00:00 AM

If there's any other log sources that may provide more insight, i'd be happy to take a look
Thanks
Any ETA on an updated xen orchestra that will support the 8.1 (beta).
I just upgraded a spare host to see if the backup speed has improved, but no luck, backups won't run so i'm guessing we need an updated version 
Merci,
Viorel
Hi Olivier,
yeap, xo from sources installed in mid december, so fairly new.
It's running on a VM with 4 vCPUS of xeon x5355 @ 2.66 Ghz
