Description: 

Views got a new way to render itself. By using \Drupal\views\Plugin\views\display\DisplayPluginBase::buildBasicRenderable()
you get back a render array without the loaded view. This is as performant as you can get.

Before


$view = views_get_view('test_view');
$build = $view->preview('display_id', $args);

After


$build = DisplayPluginBase::buildBasicRenderable('test_view', 'display_id', $args);

Note: We might improve the way how we deal with it in the future.
