How to use Eloquent without losing performance (51.39%) in Lumen 5.4?

Developing an API that must handle a high-performance website. By doing a few tests, I noticed that Eloquent usage is lowering the performance of requests in the MySQL database in 51.39% (more than half). The OS is ubuntu 16.04 and the framework is Lumen 5.4 . The query selects all cities from the cities table (5565 city).

//Rota
$app->get('cities', 'CitiesController@index');

This is Cities CitiesController controller:

namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;
use App\Models\Citie;

class CitiesController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    public function index()
    {
        return DB::select("SELECT * FROM cities");
        //return Citie::all();
    }
}

This is the Model Citie:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Citie extends Model
{
    protected $guarded=['id'];
}

I'm using POSTMAN to do the 10 requisitions for each approach (with and without Eloquent).

Com Eloquente - >  return Citie::all();
Sem Eloquente - >  return DB::select("SELECT * FROM cities");

And these are the results in milliseconds (ms):

No Eloquent:

1918
1841
1897

média - 1845.6

With Eloquent:

3449
3684
3654
3667
3546
3491
3462
3531
3614
3815
média - 3591.3

The result is that in this test the use of Eloquent is decreasing the requisite performance by 51.39% compared to the scenario without Eloquent.

Here is an example of the output:
