Memory usage question...

As far as I can tell, CI uses about 1MB on it's own. So you're at about 1.7MB. I assume you're loading some libraries, or you just have a LOT of variables. The only suggestion I can make is... make sure you're only loading libraries where needed, so don't autoload them in your config, and don't load them in your class constructors, only load them in the actual function that needs them, this will help avoid loading libraries that you don't even need.
