  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>
