|
||
<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.<2E> On the NetWare OS it is highly recommended that this directive
|
||
remain set to 0.<2E> 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>
