threadpool
Yet another experimental variant of the standard worker MPM
MPM

# Warning

This MPM is a developer playground and highly experimental, so it may or may not work as expected.

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.
