Friezes when scrolling text

There is a ScrollView with a TextView inside. On weak and medium devices, with large text, lags begin when scrolling. Is it possible to somehow optimize the text so that it does not lag?

<ScrollView android:id="@id/scrollView" android:layout_height="150.0dp" android:layout_below="@+id/nameText" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" android:layout_toRightOf="@+id/btn1" android:layout_toEndOf="@+id/btn1" android:paddingLeft="10dp" android:paddingRight="30dp" android:layout_width="400dp"> <TextView android:id="@+id/descriptionText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#ffffff" android:shadowColor="#000000" android:shadowDx="1" android:shadowDy="1" android:shadowRadius="15" android:textStyle="bold" android:textSize="17sp" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:textAppearance="?android:textAppearanceLarge" /> </ScrollView>
