Autoloading all models in CodeIgniter

Are there any disadvantages to just putting all models in $autoload['model开发者_C百科'] instead of loading them only as necessary?

You might want to take a look at the CodeIgniter Profiler Class to see how your application performs auto-loading all models versus loading them only when needed. I'd recommend looking at execution time and memory usage.
