I thought I had explained in good detail how the directives for httpd work. Here is a snippet from the apache-optimize script:

<IfModule prefork.c>
StartServers 2
MinSpareServers {$minpar_p}
MaxSpareServers {$maxpar_p}
ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000
MaxMemFree 2
</IfModule>

http://project.lxcenter.org/projects/kloxo/repository/revisi ons/master/entry/kloxo/bin/fix/apache-optimize.php

ServerLimit is always set at 256 and MaxClients is set to 256.

If $minpar_p is set to 10 and $maxpar_p is set to 25 then here is the result:

When httpd is started you will have 10 - 11 httpd processes to start with minimally. As the day goes on you will have 25 to 26 running. As the day goes further it can peak at 256 to 257 processes running. How does this optimize the memory? The min and max spare servers do not dictate what the peak httpd processes will be and therefore will not dictate peak memory usage.
