I asked in cakephp IRC, A person answer is not:

[11:05] it will not be slow, I believe it passes those around via reference

[11:05] so you have nothing to worry about

Answer 1

Lets say you want to import BComponent into AComponent.

AComponent

class AComponent extends Component {
     public $components = array('BComponent');

     public function xyz(){
           $test = $this->BComponent->abc($name);
           echo $test;
     }
}

BComponent

class BComponent extends Component {

     public function abc($name){
           return "My name is: ". $name;
     }
}

Answer 2

yes, it would need to be $components = array('Session','Auth','Custom'); Or you can use: App::import('Component', 'Custom');$Custom = new CustomComponent();

Then do CustomComponent must reload Session, Auth components? If you don't use Session or Auth inside your CustomComponent class, then no.

It will make app is very slow? No, unless you use a lot of components.
