Posix AIO can suffer from severe + limitations. For example, on some Linux versions the + real-time signals that it uses are broken under heavy load. + Other systems only allow AIO when special kernel modules are + loaded or only allow a certain system-wide amount of async + requests being scheduled. Systems based on glibc (most Linux + systems) only allow a single outstanding request per file + descriptor. </p><p>To work around all these limitations, the aio_fork module + was written. It uses forked helper processes instead of the + internal Posix AIO interface to create asynchronousity for + read and write calls. It has no parameters, it will create + helper processes when async requests come in as needed. Idle + helper processes will be removed every 30 seconds. + </p><p>This module is stackable.</p></div><div class="refsect1" title="EXAMPLES"><a name="id266837"></a><h2>EXAMPLES</h2><p>Straight forward use:</p><pre class="programlisting"> + <em class="parameter"><code>[cooldata]</code></em> + <a class="link" href="smb.conf.5.html#PATH" target="_top">path = /data/ice</a> + <a class="link" href="smb.conf.5.html#VFSOBJECTS" target="_top">vfs objects = aio_fork</a> +</pre></div><div class="refsect1" title="VERSION"><a name="id266880"></a><h2>VERSION</h2><p>This man page is correct for version 3.6.0 of the Samba suite. + </p></div><div class="refsect1" title="AUTHOR"><a name="id266889"></a><h2>AUTHOR</h2><p>The original Samba software and related utilities + were created by Andrew Tridgell.
