My original query:
   Got a 8mm DAT with a tar archive created on IBM AIX. Exracting this data on
to a SS4 is very slow. 'truss' output shows thst each 'read' call returns only
512 bytes even when the requested block size is more (10240 or 32768).
 
Conclusion:
  The tape has been written using 512-byte block size. There is nothing much I
can do about it. I can only suggest the person who created the tape-archive to
use a bigger block size next time.
