[ovirt-users] Slow VM replication

Hi everyone, When cloning a VM, I discovered that the time to close appears excessive based on the underlying platform I am using. It appears that the clone operation is not making efficient use of the network. I have seen up to 4 GBits sustained throughput by applications on VM's on the cluster. Is there a configuration I might be missing? *System specifics:* Backing store: NFS on TrueNAS running zRaid 3 on 11 spinning disks Ovirt Controller: I7 desktop General network: 1 GBit Ethernet Ovirt Host: Intel(R) Xeon(R) Silver 4216 CPU @ 2.10GHz, 2x32 cores, 256 GB RAM Data Network: 10 GBit 10GBase-Twinax, dedicated to this Host and the TrueNAS *Operation:* Copying the 60GB partition, the copy operation never exceeds 40 megabytes per second (less than 0.5 GBit), even though the dedicated 10 Gigabit data network is not otherwise busy.
