prefork [default MPM for Apache 2.0 and 1.3]

[vasanth]

[/b] Apache 1.3-based [/b]

* Multiple processes, 1 thread per process, processes handle requests.
* Used for security and stability.
* Has higher memory consumption and lower performance over the newer Apache 2.0-based threaded MPMs.
worker:

[/b]Apache 2.0-based[/b]

* Multiple processes, many threads per process, threads handle requests.
* Used for lower memory consumption and higher performance.
* Does not provide the same level of isolation request-to-request, as a process-based MPM does.
