On my experience, is very important correct values for:
  • MaxClient -> 100 Ok (it's can be more)
  • MinSpareServers -> min free instances, sugest same of StartServers
  • MaxSpareServers -> max free instances, sugest more than 60% of MaxClients
  • MaxKeepAliveRequests -> never all instances, sugest 50% of MaxClient
  • MaxRequestPerChild -> max request before kill process, set if required...

Some time ago I had make a node Monitor instances of Apache Web server, with a script to see how are use of apache web connections online. To see historical usage, I'm sugest to use it or Apache-Tools (from Apache-Security).

Evaluating your load averages, swap and CPU states, on my opinion optimize apache make good results... See your running time of httpd process:

$ grep httpd 547234 | awk '{print $8}' | sort | uniq -c | head -n 5 125 0:00 110 0:01 41 0:02 14 0:03 9 0:04
But the great info is "Parent Server Generation: XX" on server-status ... You realy need to enable this module ;)
