title: Model Loading issue with CodeIgniter
body: <p>If I load 5 models in a controller, will the <strong>connection to database</strong> will be established for all the models separately ?</p>
  
  <p>Because it is creating problem of server hanging, due to opening multiple ports for the database connection for each model.</p>
  
  <p>If there is any solution?</p>
  
  <p>Thanks in advance.</p>
