However, due to a different implementation, overlays generally don=E2=80=99t scale well (many opera= tions take a time that is proportional to the number of overlays in the buffer). If you need to affect the visual appearance of many portions in the buffer, we recommend using text properties. Should it be removed now, when overlays are equally performance with text properties?
