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

  33       <p>This MPM is a developer playground and highly experimental, so it
  34       may or may not work as expected.</p>
  35     </note>
  36
  37     <p>This is an experimental variant of the standard worker MPM.
  38     Rather than queuing connections like the worker MPM, the
  39     <module>threadpool</module> MPM queues idle worker threads and
  40     hands each accepted connection to the next available worker.</p>
  41
  42     <p>The <module>threadpool</module> MPM can't match the performance of
  43     the <module>worker</module> MPM in benchmark testing. As of 2.0.39,
  44     some of the key load-throtting concepts from the <module
  45     >threadpool</module> MPM have been incorporated into the <module
  46     >worker</module> MPM. The <module>threadpool</module> code is useful
  47     primarily as a research platform. For general-purpose use and for any
  48     production environments, use <module>worker</module> instead.</p>
