Although ActionScript can be slow, in most multimedia presentations, the assets such as graphics, audio, and video—and not the code—are often the limiting performance factor. Furthermore, the overall performance (or apparent performance from a user perspective) is also affected by download times and not just runtime execution. Of course, for a Rich Internet Application accessing a back-end database, performance might depend on the speed of database queries, data transmission, and text rendering.

Many hacks throughout this book cover ActionScript optimization. Furthermore:
