Apache Working mode

Have used a few years of Apache server, today only know there is a working mode of this matter, it seems that they have been to use smattering, the theory only may not tress.

Consult the relevant data, the Apache action mode has the following understanding, time is limited, how to configure the first not in-depth understanding

Apache Working mode:

1. Prefork is the default (default) MPM on the UNIX platform, using multiple child processes with only one thread per child process. Each process can only maintain one connection at a certain time, and is efficient, but has a large memory footprint.

2, the worker uses multiple child processes, each child process has multiple threads, each thread can only maintain one connection at a certain time, memory consumption is small, suitable for high traffic HTTP server. The downside is that if a thread crashes, the entire process will "die" with any of its threads, so ensure that a program must be recognized by the system as "every thread is safe" at run time.
