+ </div>
+
+ <p>This is an experimental variant of the standard
+ <code class="module"><a href="../mod/worker.html">worker</a></code> MPM. It uses a Leader/Followers design pattern
+ to coordinate work among threads. For more info, see <a href="http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf">http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf</a>.</p>
+
+ <p>To use the <code class="module"><a href="../mod/leader.html">leader</a></code> MPM, add
+ <code>--with-mpm=leader</code> to the configure script's arguments
+ when building the httpd.</p>
+
+ <p>This MPM depends on APR's atomic compare-and-swap operations for
+ thread synchronization. If you are compiling for an x86 target
+ and you don't need to support 386s, or you are compiling for a
+ SPARC and you don't need to run on pre-UltraSPARC chips, add
+ <code>--enable-nonportable-atomics=yes</code> to the configure
+ script's arguments. This will cause APR to implement atomic operations
+ using efficient opcodes not available in older CPUs.</p>

specified in the <code class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code> directive.
The individual threads then
listen for connections and serve them when they arrive.</p>
necessary to modify these directives from their default values.
The maximum number of clients that may be served simultaneously
is determined by multiplying the number of server processes
- that will be created (<code class="directive"><a href="../mod/mpm_common.html#numservers">NumServers</a></code>) by the maximum
+ that will be created (<code class="directive"><a href="#numservers">NumServers</a></code>) by the maximum
number of threads created in each process
(<code class="directive"><a href="../mod/mpm_common.html#maxthreadsperchild">MaxThreadsPerChild</a></code>).</p>
server recycles processes by killing old ones and launching new
ones.</p>
- <p>In addition it adds the extra ability to specify that
- specific processes should serve requests under different
- userids. These processes can then be associated with specific
- virtual hosts.</p>
+ <h3><a name="user-ids" id="user-ids">Working with different user-IDs</a></h3>
+ <p>The <code class="module"><a href="../mod/perchild.html">perchild</a></code> MPM adds the extra ability to
+ specify that particular processes should serve requests under
+ different user-IDs. These user-IDs can then be associated with
+ specific virtual hosts. You have to use one <code class="directive"><a href="#childperuserid">ChildPerUserID</a></code> directive for
+ every user/group combination you want to be run. Then you can tie
+ particular virtual hosts to that user and group IDs.</p>
+
+ <p>The following example runs 7 child processes. Two of them are run
+ under <code>user1</code>/<code>group1</code>. The next four are run
+ under <code>user2</code>/<code>group2</code> and the remaining
+ process uses the <code class="directive"><a href="../mod/mpm_common.html#user">User</a></code> and <code class="directive"><a href="../mod/mpm_common.html#group">Group</a></code>
+ of the main server:</p>
+
+ <div class="example"><h3>Global config</h3><p><code>
+ NumServers 7<br />
+ ChildPerUserID user1 group1 2<br />
+ ChildPerUserID user2 group2 4
+ </code></p></div>
+
+ <p>Using unbalanced numbers of processes as above is useful, if the
+ particular virtual hosts produce different load. The assignment to
+ the virtual hosts is easily done as in the example below. In
+ conclusion with the example above the following assumes, that
+ <code>server2</code> has to serve about twice of the hits of
+ <code>server1</code>.</p>
+
+ <div class="example"><h3>Example</h3><p><code>

+<h3>Summary</h3>
+
+ <div class="warning"><h3>Warning</h3>
+ <p>This MPM is a developer playground and highly experimental, so it
+ may or may not work as expected.</p>
+ </div>
+
+ <p>This is an experimental variant of the standard worker MPM.
+ Rather than queuing connections like the worker MPM, the
+ <code class="module"><a href="../mod/threadpool.html">threadpool</a></code> MPM queues idle worker threads and
+ hands each accepted connection to the next available worker.</p>
+
+ <p>The <code class="module"><a href="../mod/threadpool.html">threadpool</a></code> MPM can't match the performance of
+ the <code class="module"><a href="../mod/worker.html">worker</a></code> MPM in benchmark testing. As of 2.0.39,
+ some of the key load-throtting concepts from the <code class="module"><a href="../mod/threadpool.html">threadpool</a></code> MPM have been incorporated into the <code class="module"><a href="../mod/worker.html">worker</a></code> MPM. The <code class="module"><a href="../mod/threadpool.html">threadpool</a></code> code is useful
+ primarily as a research platform. For general-purpose use and for any
+ production environments, use <code class="module"><a href="../mod/worker.html">worker</a></code> instead.</p>
