 <summary>
     <p>This Multi-Processing Module (MPM) implements a hybrid
-    multi-process multi-threaded server. Each process has a fixed
+    multi-process multi-threaded server.  By using threads to serve
+    requests, it is able to serve a large number of requests with
+    less system resources than a process-based server.  Yet it
+    retains much of the stability of a process-based server by 
+    keeping multiple processes available, each with many threads.</p>
+
+    <p>The most important directives used to control this MPM are
+    <directive module="mpm_common">ThreadsPerChild</directive> and
+    <directive module="mpm_common">MaxClients</directive>.  By multiplying
+    together the value of these directives you define the total number
+    of simultaneous connections that the server can handle.</p>

+    <p>Each process has a fixed
     number of threads. The server adjusts to handle load by
     increasing or decreasing the number of processes.</p>
 
     <p>A single control process is responsible for launching child

-    as specified in the <code>ThreadsPerChild</code> directive. The
-    individual threads then listen for connections and serve them
-    when they arrive.</p>

     <p>Apache always tries to maintain a pool of <em>spare</em> or
     idle server threads, which stand ready to serve incoming
     requests. In this way, clients do not need to wait for a new
     threads or processes to be created before their requests can be
     served. Apache assesses the total number of idle threads in all
-    processes, and forks or kills processes to keep this number
-    within the boundaries specified by <code>MinSpareThreads</code>
-    and <code>MaxSpareThreads</code>. Since this process is very
-    self-regulating, it is rarely necessary to modify these
-    directives from their default values. The maximum number of
+    processes, and forks or kills processes to keep this number within

+    module="mpm_common">MaxSpareThreads</directive>. Since this
+    process is very self-regulating, it is rarely necessary to modify
+    these directives from their default values. The maximum number of
     clients that may be served simultaneously is determined by
     multiplying the maximum number of server processes that will be
-    created (<code>MaxClients</code>) by the number of threads
-    created in each process (<code>ThreadsPerChild</code>).</p>

-    <p>While the parent process is usually started as root under
-    Unix in order to bind to port 80, the child processes and
-    threads are launched by Apache as a less-privileged user. The
-    <code>User</code> and <code>Group</code> directives are used to
-    set the privileges of the Apache child processes. The child
-    processes must be able to read all the content that will be
-    served, but should have as few privileges beyond that as
