title: PHP codeigniter Memory usage around 4mb
body: <p>I made the mistake of getting into the habit of autoloading a bunch of libraries, models..etc, when I don't need to. It is too hard to trace down all the cases to make sure everything is available and not broken. I am estimating the autoloading is causing 1-2 MB of extra resources per script. The total memory usage for my script is around 4Mb. (I used the profiler and disabled autoloading and saw that it dropped 1-2mb)</p>
  
  <p>Is this something to worry about? The server I am running this on has 1gb of ram and doesn't ever seem to be under heady load.</p>
  
  <p>Is this a bad thing? Am I worrying too much?</p>
