Too many movie clips on the stage

Good morning,

I have a game where I’m trying to show weather effects, specifically wind. The wind can go in all 8 directions (N, S, W, SW, etc…) and can change direction. To show the wind direction, I have an array of Movie Clips shaped like leaves that continuously loop across the screen. The only thing is, the array contains about 25-50 leaves, and having that many on the stage at once sloooooooooooows everything down. Is there a better way to put multiple copies of the same MC on stage at once, without everything slowing down so much?

Thanks!
