I don't have LTO, but I've recently tuned up my DLT's by increasing the
buffer settings - some systems with very compressable data can get to
10-11 MB/sec where they used to be about half that speed.

My settings are:

::::::::::::::
/usr/openv/netbackup/NET_BUFFER_SZ
::::::::::::::
262144
::::::::::::::
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS
::::::::::::::
64
::::::::::::::
/usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS
::::::::::::::
524288
