    <p>This Multi-Processing Module (MPM) implements an exclusively
    threaded web server that has been optimized for Novell
    NetWare.</p>

    <p>The main thread is responsible for launching child
    worker threads which listen for connections and serve them when they
    arrive. Apache always tries to maintain several <em>spare</em>
    or idle worker threads, which stand ready to serve incoming
    requests. In this way, clients do not need to wait for a new
    child threads to be spawned before their requests can be
    served.</p>

    <p>The <code>StartThreads</code>, <code>MinSpareThreads</code>,
    <code>MaxSpareThreads</code>, and <code>MaxThreads</code>
    regulate how the main thread creates worker threads to serve
    requests. In general, Apache is very self-regulating, so most
    sites do not need to adjust these directives from their default
    values. Sites which need to serve more than 250 simultaneous
    requests may need to increase <code>MaxThreads</code>, while
    sites with limited memory may need to decrease
    <code>MaxThreads</code> to keep the server from thrashing (spawning and
    terminating idle threads). More information about
    tuning process creation is provided in the <a href="../misc/perf-tuning.html">performance hints</a>
    documentation.</p>

    <p><code>MaxRequestsPerChild</code> controls how frequently the
    server recycles processes by killing old ones and launching new
    ones.  On the NetWare OS it is highly recommended that this directive
    remain set to 0.  This allows worker threads to continue servicing
    requests indefinitely.</p>

    ports Apache uses</a>.</p>

    <p>This directive tells the server what stack size to use for
    each of the running threads. If you ever get a stack overflow
    you will need to bump this number to a higher setting.</p>
