EDIT: I've rewritten this question, but the topic is the same.
How can I use the memory usage tool in the Joomla! Debug Console? By that I mean, when do people look at this and how do people know when Joomla is using an unusual amount? (especially since there doesn't seem to be any references to compare too?)
Currently my test server is running Joomla 2.5x on Apache with 1 user (me) accessing the site. Memory usage is 18MB of ram. This could be normal, great or poor. I have no idea.
Searching the net, I found some mention of Joomla memory usage at http://www.joomlapolis.com/forum/153-professional-member-support/222168-excessive-resource-use?limitstart=0
