  31. <h3>Summary</h3>
  32.  
  33.     <p>This Multi-Processing Module (MPM) implements an exclusively
  34.     threaded web server that has been optimized for Novell
  35.     NetWare.</p>
  36.  
  37.     <p>The main thread is responsible for launching child
  38.     worker threads which listen for connections and serve them when they
  39.     arrive. Apache always tries to maintain several <dfn>spare</dfn>
  40.     or idle worker threads, which stand ready to serve incoming
  41.     requests. In this way, clients do not need to wait for a new
  42.     child threads to be spawned before their requests can be
  43.     served.</p>
  44.  
  45.     <p>The <code class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code>,
  46.     <code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code>,
  47.     <code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code>, and
  48.     <code class="directive"><a href="#maxthreads">MaxThreads</a></code>
  49.     regulate how the main thread creates worker threads to serve
  50.     requests. In general, Apache is very self-regulating, so most
  51.     sites do not need to adjust these directives from their default
  52.     values. Sites with limited memory may need to decrease <code class="directive"><a href="#maxthreads">MaxThreads</a></code> to keep the server from
  53.     thrashing (spawning and terminating idle threads). More information
  54.     about tuning process creation is provided in the <a href="../misc/perf-tuning.html">performance hints</a>
  55.     documentation.</p>
  56.  
  57.     <p><code class="directive"><a href="../mod/mpm_common.html#maxrequestsperchild">MaxRequestsPerChild</a></code>
  58.     controls how frequently the server recycles processes by killing old
  59.     ones and launching new ones. On the NetWare OS it is highly
  60.     recommended that this directive remain set to 0. This allows worker
  61.     threads to continue servicing requests indefinitely.</p>
