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.

  Joshua.
