Description: This FAQ describes performance issues during Duplication from VDL to physical tape drive.
Symptoms:
When using a physical tape library connected directly via SCSI to the NetVault server, the duplication phase can some time be very slow.
Typically the Phase 1 is done on VDL then the phase 2 on LTO drive, although no network traffic is involved the transfer rate is very low: 1 Mb/s
