I am reading some ansi tapes on a cypher 9 track tape. Performance
is terrible. The tape drive saws back and forth, moving only an inch
or so each cycle. How can I improve performance ? I tried using
bstream, but ansitape won't read from standard input. How can
I determine the proper blocking factor to use to match tape blocks
with host blocking buffers ?


This is agony! It is taking hours to read each tape!

Help !
