| <h3>Summary</h3> |
| |
| <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 <dfn>spare</dfn> |
| 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 class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code>, |
| <code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code>, |
| <code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code>, and |
| <code class="directive"><a href="#maxthreads">MaxThreads</a></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 with limited memory may need to decrease <code class="directive"><a href="#maxthreads">MaxThreads</a></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 class="directive"><a href="../mod/mpm_common.html#maxrequestsperchild">MaxRequestsPerChild</a></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> |

| <p>The <code class="directive">MaxThreads</code> directive sets the desired |
| maximum number worker threads allowable. The default value is |
| also the compiled in hard limit. Therefore it can only be lowered, |
| for example:</p> |
| |
| <div class="example"><p><code> |
| MaxThreads 512 |
| </code></p></div> |

| </table> |
| <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> |
