I am creating sites and importing SWF files made from programs like Swift 3D and whatnot. It really bogs down my animations and SWiSH effects. To the point where it is unplayable.

How can correct this, or is it just a computer issue (lack of memory, etc...)
Here's what I have checked:
All my SWF's are small (example - 2KB, 8KB, etc...)

Any help?
