<description>Yet another experimental variant of the standard
<module>worker</module> MPM</description>
<status>MPM</status>

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