My vault duplications are running at up to 160MB/s. My environment is Windows based and we have a 4 LT03 drive HP library.
I did try turning on multiplexing but found that the write throughput got worse the more I multiplexed so I have turned it back off for the moment. The buffers will have an affect on performance. FWIW mine are set to:- C:\..\VERITAS\NetBackup\db\config\SIZE_DATA_BUFFERS_DISK 1048576 C:\..\VERITAS\NetBackup\db\config\NUMBER_DATA_BUFFERS 64 C:\..\VERITAS\NetBackup\db\config\ NUMBER_DATA_BUFFERS_DISK 64 C:\..\VERITAS\NetBackup\db\config\ SIZE_DATA_BUFFERS 262144 C:\..\VERITAS\NetBackup\NET_BUFFER_SZ 1048576 What read speeds are you getting during the duplication process? If you have a look in the 'All log entries' report in the gui you should see a figure for the read as well as the write process after each image is duplicated.
