33 <p>This Multi-Processing Module (MPM) implements an exclusively
34 threaded web server that has been optimized for Novell
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 HTTP Server 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
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 httpd 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>
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>
