Check your buffer settings. This, and a demux source, made a difference for
me.

FWIW: I get much better performance on my DLT7k (ultra-diff) than your
1mb/sec rates.

Subject: [Veritas-bu] duplication
I don't duplicate much but does it always run slow? I am seeing an
average read/write of 1mb/sec for a duplication on dlt7k drives attached
to the master server. The primary copy is an ndmp backup so there's no
multiplexing involved.
