Hi!

I was reading an interesting document
http://httpd.apache.org/docs/2.0/misc/perf-tuning.html about MPM and I would
like to clarify a doubt regarding the concept of connection:
    *  The worker MPM uses multiple child processes with many threads each.
Each thread handles one connection at a time. Worker generally is a good
choice for high-traffic servers because it ha
s a smaller memory footprint than the prefork MPM.
    * The prefork MPM uses multiple child processes with one thread each.
Each process handles one connection at a time. On many systems, prefork is
comparable in speed to worker, but it uses more memory. Prefork's threadless
design has advantages over worker in some situations: it can be used with
non-thread-safe third-party modules, and it is easier to debug on platforms
with poor thread debugging support.

What means "Each process/thread handles one connection at a time?" A
connection is a request made by the client? A thread just handle a request?

Thanks

Best Regards
