Flash: Web_Development: RIA: Increase the the frame rate of your Flash movies
Guy Watson recently wrote an interesting article for the MX Developer's Journal discussung ways to increase performance of Flash movies. The article provides useful information on the new Bitmap Caching feature in the latest Flash player. If used properly, the Bitmap Caching feature can increase the movie's performance by reducing the amount of work that the renderer must perform on every frame. Essentially, it works by converting a movie clip's content into a bitmap copy, which is then stored in memory. The renderer displays the bitmap copy of the clip instead of processing the vector data of the clip for every frame. This is useful for clips that do not contain changing content or are being animated (at which point a new bitmap copy is created). The Bitmap Caching feature can be turned on and off in the development environment or via Actionscript.
Take a look at the article, which has some sample code provided:
