Apache MPM event

Available Languages:  en 

Description:An experimental variant of the standard worker MPM
Status:MPM
Module Identifier:mpm_event_module
Source File:event.c

Summary

Warning

This MPM is experimental, so it may or may not work as expected.

To use the event MPM, add --with-mpm=event to the configure script's arguments when building the httpd.

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 --enable-nonportable-atomics=yes to the configure script's arguments. This will cause APR to implement atomic operations using efficient opcodes not available in older CPUs.
