Symfony2 dependency Injection : performances impact - performance

Question

I'm refactoring one of my controller to make it a service and I want to know if there is a performance impact to not inject whole service container into my controller.
Is this is more efficient :
innova.path.controller:
class: %innova.controller.path.class%
arguments:
entityManager: #doctrine.orm.entity_manager
session: #session
securityContext: #security.context
router: #router
translator: #translator
pathManager: #innova.manager.path_manager
calls:
- [setRequest, ["#?request="]]
scope: request
than this, for example ?
innova.path.controller:
class: %innova.controller.path.class%
arguments: [#service_container]

Answer 1

Official documentation explicitly tell to not inject whole DIC into a Controller (thanks #NHG for link).
Section How to work with scopes :
Injecting the whole container into a service is generally not a good
idea (only inject what you need).
But in section Service container :
When you ask for the my_mailer service from the container, the
container constructs the object and returns it. This is another major
advantage of using the service container. Namely, a service is never
constructed until it's needed. If you define a service and never use
it on a request, the service is never created. This saves memory and
increases the speed of your application. This also means that there's
very little or no performance hit for defining lots of services.
Services that are never used are never constructed.
So injecting the whole DIC to controller will not have performances impact because only the services used in controller are instanciated.

The idea of using controllers as service is injecting only necessery services. Standard controller extends Symfony\Bundle\FrameworkBundle\Controller\Controller which extending Symfony\Component\DependencyInjection\ContainerAware. So, injecting whole container is makes no sense...
Generally, injecting less service is more efficient than injecting whole container.
Additionally you should familiarize with base Symfony2 Controller class.
