Externally loaded swf slows rollover buttons

I beginning to create a portfolio online. I have a pretty standard setup so far. I have a main swf which loads external swfs. One of my externally loaded swfs loads another external swf. When it does, my rollover animated buttons are slow in the main.swf. Any ideas. Memory issue i guess. I’ve attached the swfs.

Any suggestions? Memory issue I assume. Thanks.

I don’t see the swf’s you attached.
