Add important Doctrine statistics:
- Count managed entities
 - Count lazy loaded entities
 - Hydration time by hydrator and query
 - Group queries by query string, show differents parameters used by same query string
 - Count different query string used
 
composer require --dev steevanb/doctrine-stats ^2.0If you want to add hydration time to your statistics:

}If you want to add lazy loaded entities to your statistics:
# app/config/config_dev.yml
parameters:
    doctrine.orm.entity_manager.class: Steevanb\DoctrineStats\Doctrine\ORM\EntityManagerTo retrieve statistics, you need to register Steevanb\DoctrineStats\EventSubscriber\DoctrineEventSubscriber in your event manager.
If you want to add lazy loaded entities to your statistics, you need to overload default EntityManager, with Steevanb\DoctrineStats\Doctrine\ORM\EntityManager.
