Thanks Josh, I will take a look. I did some serious
fine tuning in the robots.txt file and that has cut down the cpu usage a bit
(running about 0.25-1.00 1 minute load now), so was looking at the memory
footprint of the httpd process itself.
Anyways, thank for the link, reading it
now.

I'm not sure what you really expect of us. To figure out if a
module
can be removed, just go to its page in the documentation and see
if
you are using any of its features/directives. That can't be done
over
a mailing list, although it does look like there are at least a
dozen
modules there that you probably aren't using. A list of the
core
modules that almost everyone uses is here:
http://httpd.apache.org/docs/2.2/misc/perf-tuning.html#modules
As
far as how much that will help, my guess is that it will have a
relatively
small effect. When you are using heavy-duty stuff like php
and cgi, all the
tuning you can imagine in apache is going to be
washed out by the overhead
of your dynamic content. It still may be
worthwhile to clean up unused
modules in order to save a little
memory, but it won't have a large effect.
If performance is inadequate
you need to either optimize your dynamic
content or get more
hardware.
