    The atime of a file is supposed to change whenever the data blocks of a
    file are being read. This can be costly performance-wise when an
    application regularly accesses a very large number of files or
    directories.
   </para>
   <para>
    Some Unix filesystems can be mounted with atime updates disabled to
    increase the performance of such applications; USENET news spools are a
    common example. On such filesystems this function will be useless.
