I'm trying to set the MaxClients directive in my httpd.conf and I've read that the best way to do it is to calculate the amount of memory an apache process uses and divide that into the memory I have available for apache. From top, the "RSS" for my apache processes seems to be between 15Mb and 21Mb. I do have a large number of DSO Modules in my httpd.conf and have read that these are loaded once and shared across all the processes. Is the RSS figure the right figure to use? Or does that include the DSOs for each process (and if so, how do I find the real figure)?
