Query on mod_fast_cgi| Loading modules not required | MaxRequestPerChild

["Arnab Ganguly" <aganguly01@xxxxxxxxx>]

Hi All,
I have couple of  basic question from my end.I am using Apache2.2 with MPM=worker and the OS is Red-hat release 3.0.

1) What is the usage of mod_fast_cgi ?

2)What
is the  impact on the httpd-binary if we Load mdoules which may not be
relevant for a particular requirement?Like for example if I don't load
mod_server_status which monitors the Apache thread and process
information?

3)What is the impact if the MaxRequestPerChild is kept non
zero and the apache server is made to run for a longer duration?Any
memory issues we are going to face?

Looking forward response.
Thanks in advance.
