    <p>The <code class="module"><a href="../mod/event.html">event</a></code> Multi-Processing Module (MPM) is

    designed to allow more requests to be served simultaneously by

    passing off some processing work to supporting threads, freeing up

    the main threads to work on new requests.  It is based on the

    <code class="module"><a href="../mod/worker.html">worker</a></code> MPM, which implements a hybrid

    multi-process multi-threaded server.  Run-time configuration

    directives are identical to those provided by

    <code class="module"><a href="../mod/worker.html">worker</a></code>.</p>



    <p>To use the <code class="module"><a href="../mod/event.html">event</a></code> MPM, add

      <code>--with-mpm=event</code> to the <code class="program"><a href="../programs/configure.html">configure</a></code>

      script's arguments when building the <code class="program"><a href="../programs/httpd.html">httpd</a></code>.</p>



    <p>This MPM depends on <a class="glossarylink" href="../glossary.html#apr" title="see glossary">APR</a>'s atomic

    compare-and-swap operations for thread synchronization. If you are

    compiling for an x86 target and you don't need to support 386s, or

    you are compiling for a SPARC and you don't need to run on

    pre-UltraSPARC chips, add

    <code>--enable-nonportable-atomics=yes</code> to the

    <code class="program"><a href="../programs/configure.html">configure</a></code> script's arguments. This will cause

    APR to implement atomic operations using efficient opcodes not

    available in older CPUs.</p>

<h2><a name="how-it-works" id="how-it-works">How it Works</a></h2>

    <p>This MPM tries to fix the 'keep alive problem' in HTTP. After a client

    completes the first request, the client can keep the connection

    open, and send further requests using the same socket. This can

    save signifigant overhead in creating TCP connections. However,

    Apache traditionally keeps an entire child process/thread waiting

    for data from the client, which brings its own disadvantages. To

    solve this problem, this MPM uses a dedicated thread to handle both

    the Listening sockets, and all sockets that are in a Keep Alive

    state.</p>



    <p>The MPM assumes that the underlying <code>apr_pollset</code>

    implementation is reasonably threadsafe. This enables the MPM to

    avoid excessive high level locking, or having to wake up the listener

    thread in order to send it a keep-alive socket. This is currently

    only compatible with KQueue and EPoll.</p>

    <p>This MPM does not perform well on older platforms which lack good

    moot.</p>

      <li>To use this MPM on FreeBSD, FreeBSD 5.3 or higher is recommended.

      However, it is possible to run this MPM on FreeBSD 5.2.1, if you

      use <code>libkse</code> (see <code>man libmap.conf</code>).</li>



      <li>For NetBSD, at least version 2.0 is recommended.</li>



      <li>For Linux, a 2.6 kernel is recommended. It is also necessary to

      ensure that your version of <code>glibc</code> has been compiled

      with support for EPoll.</li>
