Doctrine 2 way too slower than Laravel's Eloquent - doctrine-orm

Question

I'm trying to use Doctrine 2 (LaravelDoctrine) instead of Eloquent.
Performing simple query of getting paginated data:
// Doctrine
$orders = $this->orderRepository->paginateAll(50);
// Eloquent
$orders = $this->orders->paginate(50);
I end up with Doctrine queries taking too much time (info from Laravel Debugbar):
Doctrine queries took 3.86s
1.79s
SELECT DISTINCT id_0 FROM (SELECT o0_.id AS id_0, o0_.customer_id AS customer_id_1, o0_.customer_ref AS customer_ref_2, ... FROM orders o0_) dctrn_result LIMIT 50 OFFSET 0
16.63ms
SELECT o0_.id AS id_0, o0_.customer_id AS customer_id_1, o0_.customer_ref AS customer_ref_2, ... FROM orders o0_ WHERE o0_.id IN (?)
2.05s
SELECT COUNT(*) AS dctrn_count FROM (SELECT DISTINCT id_0 FROM (SELECT o0_.id AS id_0, o0_.customer_id AS customer_id_1, o0_.customer_ref AS customer_ref_2, ... FROM orders o0_) dctrn_result) dctrn_table
Eloquent queries took 50.38ms
36.73ms
select count(*) as aggregate from `orders`
13.65ms
select * from `orders` limit 50 offset 0
I'm not pasting whole doctrine queries here as there's 65 columns in the table, but they all used with 'AS', identically to mentioned columns.
Is this is intended Doctrine 2 behavior to be so slow or am I missing something?
I used annotations as Meta Data for mapping and Doctrine\ORM\EntityRepository for accessing the data.
Thank you in advance.
Best Regards.
