Very slow query

I am dummy with sql.

$data = $model1->model2()->has('model3')->withCount('model3')->orderBy('name')->get();

If model 3 has up to 2M rows, indexes in id's. Model1 and model2 pivot with indexes od id's. Why does it take up to 5000ms to query it? Is there a better approach? Thanks

select
  `model2`.*,
  (
    select
      count(*)
    from
      `model3`
    where
      `model2`.`id` = `model3`.`model2_id`
      and `enabled` = 1
  ) as `model3_count`,
  `model1_model2`.`model1_id` as `pivot_model1_id`,
  `model1_model2`.`model2_id` as `pivot_model2_id`
from
  `model2`
  inner join `model1_model2` on `model2`.`id` = `model1_model2`.`model2_id`
where
  `model1_model2`.`model1_id` = 430
  and exists (
    select
      *
    from
      `model3`
    where
      `model2`.`id` = `model3`.`model2_id`
      and `enabled` = 1
  )
order by
  `name` asc
