Magento 2 - Which is faster - load product by ID via ProductRepositoryInterface, ProductFactory or object manager

Question

Approaching loading products from performance point of view. Assuming you want to echo out standard attribute values such as SKU, name, etc. and you are dealing with a large number of products and you are loading them within a loop (assume not a product collection). Anyone know which is the fastest method?

ObjectManager (Yes I know you're not supposed to use this method)

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->get('Magento\Catalog\Model\Product')->load($product_id);

ProductRepositoryInterface

protected $productRepository; 
    ...
    public function __construct(
    ...
    \Magento\Catalog\Api\ProductRepositoryInterface $productRepository
    ) {
        ...
        $this->productRepository= $productRepository;
        ...
    }

    $product = $this->productRepository->getById($id);

ProductFactory

protected $productFactory;  
    ...
    public function __construct(
        ...
        \Magento\Catalog\Model\ProductFactory $productFactory
    ) {
        ...
        $this->productFactory = $productFactory;
        ...
    }

$product = $this->productFactory->create()->load($id);

Answer 1

In this scenario we can compare only two option ProductRepositoryInterface and Product Factory. So these two options the ProductRepositoryInterface is faster then Product Factory the reason behind that is ProductRepositoryInterface is getting the Data using API
