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 which essentially makes Posix AIO useless on systems - using the glibc implementation.</p><p>To work around all these limitations, the aio_pthread module - was written. It uses a pthread pool instead of the - internal Posix AIO interface to allow read and write calls - to be process asynchronously. A pthread pool is created - which expands dynamically by creating new threads as work is - given to it to a maximum of 100 threads per smbd process. - To change this limit see the "aio num threads" parameter - below. New threads are not created if idle threads are - available when a new read or write request is received, - the new work is given to an existing idle thread. Threads - terminate themselves if idle for one second. - </p><p> - Note that the smb.conf parameters <code class="literal">aio read size</code> - and <code class="literal">aio write size</code> must also be set appropriately - for this module to be active. - </p><p>This module MUST be listed last in any module stack as - the Samba VFS pread/pwrite interface is not thread-safe. This - module makes direct pread and pwrite system calls and does - NOT call the Samba VFS pread and pwrite interfaces.</p></div><div class="refsect1" title="EXAMPLES"><a name="id266856"></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#AIOREADSIZE" target="_top">aio read size = 1024</a> - <a class="link" href="smb.conf.5.html#AIOWRITESIZE" target="_top">aio write size = 1024</a> - <a class="link" href="smb.conf.5.html#VFSOBJECTS" target="_top">vfs objects = aio_pthread</a> -</pre></div><div class="refsect1" title="OPTIONS"><a name="id265817"></a><h2>OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">aio_pthread:aio num threads = INTEGER</span></dt><dd><p>Limit the maximum number of threads per smbd that - will be created in the thread pool to service IO requests. - </p><p>By default this is set to 100.</p></dd></dl></div></div><div class="refsect1" title="VERSION"><a name="id265844"></a><h2>VERSION</h2><p>This man page is correct for version 3.6.3 of the Samba suite. - </p></div><div class="refsect1" title="AUTHOR"><a name="id265854"></a><h2>AUTHOR</h2><p>The original Samba software and related utilities - were created by Andrew Tridgell.
