| <p>This MPM is experimental, so it may or may not work |
| as expected.</p> |
| </note> |
| |
| <p>This is an experimental variant of the standard |
| <module>worker</module> MPM. It uses a Leader/Followers design pattern |
| to coordinate work among threads. For more info, see <a |
| href="http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf" |
| >http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf</a>.</p> |
| |
| <p>To use the <module>leader</module> MPM, add |
| <code>--with-mpm=leader</code> to the <code>configure</code> script's |
| arguments when building the <code>httpd</code>.</p> |
| |
| <p>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 |
| <code>--enable-nonportable-atomics=yes</code> to the <code>configure</code> |
| script's arguments. This will cause APR to implement atomic operations |
| using efficient opcodes not available in older CPUs.</p> |
