title: Codeigniter: Will using $this->load->database() multiple times result in multiple connections?
body: <p>I was thinking about removing the database library from my autoload file. I am caching everything on the page so I do not need to connect to the db every time and I figured it is a waste of speed if I have CI connect to the db anyway.</p>
  
  <p>My Question is now: if I for e.g. load the database in MY_Model <code>$this-&gt;load-&gt;database()</code> without parameters (they come from the config file), will a new connection be established for every model I use in a controller?</p>
  
  <p>Or will it be like helpers that are only loaded once? </p>
