It sounds like allowing multiple data streams on any box with multiple file
systems on the same physical drive device is a bad idea...correct?

Say I have a Sun server w/ the following mount points and slices:

   /             c0t0d0s0
   /usr          c0t0d0s1
   /export/home  c0t0d0s3
   /data         c0t1d0s0

Using the ALL_LOCAL_DRIVES file list directive and multiple streams will
reduce my performance since four jobs will be created, three of which are on
the same physical drive (and potentially could be active at the same time)?
A better solution would be:

   NEW_STREAM
   /
   /usr
   /export/home
   NEW_STREAM
   /data

Correct?

Thanks for your patience. I'll get it shortly!
