Problem
Performance can be affected by keeping Movieclips just off stage, learn how to avoid this.
Solution
Keep non-essential MovieClips at least 1000 pixels off the edges of the stage.
Detailed explanation
Objects placed just off the stage are added to the rendering queue this causes a reduction in performance. By placing the objects very far off the stage a performance improvement can be achieved as the objects are not added to the queue.
Most developers do not realize placing their objects next to the stage will cause a performance hit. They often leave items there that have no visual representation, service handlers, key handlers etc.
Essentially Flash is being smart, MovieClips just off stage are expected to be used soon. Therefore if you place them there the player places them in a rendering queue ready to be drawn on the screen.
