- <title>DESCRIPTION</title>
-
- <para>This VFS module is part of the
- <citerefentry><refentrytitle>samba</refentrytitle>
- <manvolnum>7</manvolnum></citerefentry> suite.</para>
-
- <para>The <command>aio_fork</command> VFS module enables async
- I/O for Samba on platforms where the system level Posix AIO
- interface is insufficient. 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. </para>
-
- <para>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.
- </para>
-
- <para>This module is stackable.</para>
