<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
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>The <code class="directive">MaxSpareThreads</code> directive sets the
desired maximum number of <em>idle</em> worker threads. An idle
worker thread is one which is not handling a request. If there are
more than MaxSpareThreads idle, then the main thread will kill off
the excess worker threads.</p>
<p>Tuning of this parameter should only be necessary on very
busy sites. Setting this parameter to a large number is almost
always a bad idea.</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>
