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?
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
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.
