Here is a screenshot of my usage today on an idle unfinished cms drupal site with a maximum of 14 added modules besides core and no activity or users.
As you can see I am at my limit which is crazy so I need to limit memory usage of apache and mysql and php because my VPS is smallest one which should suit my current needs.
My system file my.cnf does not have a list of parameters as I've seen posted elsewhere but this is the file which apparently will lessen usage of memory amongst other things I've read like memory leaks and apache MPM workers vs apache prefork which seems to be what I have.
So how can I significantly reduce memory usage without removing apache or php5?
I am using mysql version 5.1.66 and looks like innodb and show variable yabbit.net/mysql.txt
