Join files

I have a question on Join files:

    The first is on joining files.  I have two physical files that have been
    joined.  The first one is a customer master file that has one member and
    582363  total records (no deleted records).  The second file is a
control
    file that has 8 records (40 deleted records) and one member.  A join
logical
    was created over the two physical files.  The customer file is the first
    file and is joined to the second by customer number.  The files are
sorted
    by customer name and number.  In my program I allow the user to type in
the
    customer name.  I then set lower limits to the join file by the entered
    information and read it.  I then display information from the join.  The
    problem is that it takes over 5 minutes to display the information.
Does
    anyone have any suggestions on what the problem is?  Is a join a valid
    option in this program?  There was debate over the use of a join file.
