This is like a question I'd send to ye-ole sun-managers list, but here
goes.

I have an AIT2 drive on an E250 that I need to dump about 300gig of data
to.  The AIT2 specs say that with a compressed volume (/dev/rmt/1c) I
should get about 120 gig on a single tape.

So far so good.

The problem is, the write speed is PAINFULLY slow.  We're using gnutar,
and the command is:

tar -c -M -f /dev/rmt/1c -L 120000000 .

With that command its taking 8-12 HOURS to run a single tape.  Not good.

I'm guessing a blocking factor problem.  Any ideas what an appropriate
blocking factor for this arrangement should be?

Thanks!
