почему добавление фрагмента карты поддержки xml замедлит отображение моего фрагмента?

У меня есть макет ограничения внутри представления прокрутки. и внутри этого макета ограничений у меня есть фрагмент карты поддержки.

Я пытаюсь найти, что заставляет мое приложение работать медленно. для отображения фрагмента, содержащего карту (поддерживающий фрагмент карты), требуется около 1,5 секунды. Я имею в виду, что когда я заменяю фрагмент A на фрагмент B (у которого есть карта), это займет слишком много времени, через 1-2 секунды, затем на экране появится фрагмент B.

вот мой xml

    </androidx.constraintlayout.widget.ConstraintLayout>

Я попытался закомментировать все коды в моем onCreateView. так что этот фрагмент ничего не сделает. и тем не менее, мое приложение медленно отображается при показе этого фрагмента.

но когда я пытаюсь удалить фрагмент карты поддержки из моего xml, я имею в виду эту часть:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
                  xmlns:tools="http://schemas.android.com/tools"
                  android:layout_width="0dp"
                  android:layout_height="180dp"
                  android:id="@+id/map_event_detail"
                  tools:context=".Activities.MainActivity"
                  android:name="com.google.android.gms.maps.SupportMapFragment"
                  android:layout_marginTop="24dp"
                  app:layout_constraintTop_toBottomOf="@+id/line4_view_event_detail"
                  android:layout_marginStart="16dp"
                  app:layout_constraintStart_toStartOf="parent"
                  android:layout_marginEnd="16dp"
                  app:layout_constraintEnd_toEndOf="parent"/>

это ускорит рендеринг моего приложения. так почему это произошло или есть какие-либо альтернативы для решения этой проблемы?

Я имею в виду, чтобы показать карту в макете ограничения внутри представления прокрутки?

вот мой код:

    override fun onAttach(context: Context) {
        super.onAttach(context)

        mContext = context
        activity?.let { mActivity = it }

    }
