I'm not familiar with a 'nice'. Can you elaborate on that? I looked
through the modules in httpd.conf and there are several that I don't think I
need, yet are not familiar with exactly what they do to make an informed
decision to remove them. I looked a couple up on the apache site and their
descriptions. I may do some testing and see if removing them has any
affect. What is interesting to me is that they start of fairly small (.1
and .2 percent) and by noon they are 4.5 and 6.2 etc. I don't understand
what they are holding. I looked up the modules for apache to cache pages
and I don't have them in my configs. The pages on the site are 90% dynamic
in origin (PHP). So I don't see much need to hold any pages in memory if
that is what is going on. I just don't see where I can adjust that control
(if it is adjustable). Again, I haven't seen any evidence that there is an
impact on performance, it just doesn't look very comforting to see the
virtual memory at 60%. It also seems like overkill to see around 400 mb as
not available for a machine that serves at most 15 people.
Oh well, I guess I'll give you guys a rest. Anyway, I welcome any ideas or
insite on what that increase indicates.

Depends if you installed the httpd with modules like mod_perl, mod_ssl, etc.
>From experience, adding in mysql and xml support in addition to the above
modules can result in higher process loads. If you need the modules, be
prepared for the CPU resources to get eaten up. As for the child processes,
if you are running lot of web services, it might be best to increase these
or risk running into longer wait times for data updates, etc.
You might also consider putting a different 'nice' on the httpd process
overall as well.
