Flash Optimization

I couldn’t really find any good posts on how to optimize your flash site, project or whatever you re doing in flash. So i thought maybe you guys should post your best tips on optimal site structure when building a site, like loading external swfs, avoiding alpha and motion tween, smoother animations, faster loading times etc.
Just post your tips for better flashing!:beer:

I’ll go, try to divide up the site and load external swf’s rather than having one huge swf.
Always use a preloader.

Use actionscript instead of tweening objects.

Don’t animate dynamic textboxes, looks like you are running on 3fps…

Any actionscript tips?
