<description>
  <para>If this integer parameter is set to a non-zero value,
    Samba will write to files asynchronously when the request size is bigger
    than this value. Note that it happens only for non-chained and non-chaining
    reads and when not using write cache.</para>
  <para>The only reasonable values for this parameter are 0 (no async I/O) and
    1 (always do async I/O).</para>
  <para>Compared to <smbconfoption name="aio read size"/> this parameter has
    a smaller effect, most writes should end up in the
    file system cache. Writes that require space allocation might
    benefit most from going asynchronous.</para>
