I don't know how NET_BUFFER_SZ would help your bpduplicate process, since
this is on the same machine.

I don't even know if SIZE_DATA_BUFFERS or NUMBER_DATA_BUFFERS would help on
the same machine...

Is it a requirement that you 'demultiplex' the images?  If not how long does
it take to do a duplication that maintains the MPX?

I'd actually run that as a test...to see how long that takes.  If it is
still long, then it wouldn't be the duplication process, but perhaps
something else.

Subject: [Veritas-bu] bpduplicate taking XX hours, too long


Someone recently posted that their duplication process was taking much
longer than they would have expected. We are finding that the case on
-some- of our duplications here as well. When they crawl they really
CRAWL.  Originals and duplicates both allow for multiplexing. Media and
master server same machine. HP-UX 10.20 , DataCenter 3.4. Input tapes
usually on a STK 9730, output tapes usually on Adic Fastor 7
One response was to change the NET_BUFFER_SZ to 262144 .  What are the
odds that this could help us here?
