| Threadpool MPM: |
| This is an experimental variant of the standard worker MPM. |
| Rather than queuing connections like the worker MPM, the threadpool |
| MPM queues idle worker threads and hands each accepted connection |
| to the next available worker. |
| |
| The threadpool MPM can't match the performance of the worker MPM |
| in benchmark testing. As of 2.0.39, some of the key load-throtting |
| concepts from the threadpool MPM have been incorporated into the |
| worker MPM. The threadpool code is useful primarily as a research |
| platform; for general-purpose use, and for any production environments, |
| use worker instead. |
