We've had this code in for long enough that we should enable it by default. Modern clients do overlapping I/O, we should utilize that if possible. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Andreas Schneider <asn@samba.org>

<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>
