Flash Overload?

Hi all.
I am currently building a flash site, and as you may all know, I have a “index” swf, and from there it loads the other “content” swfs.

Here is the problem.
When the index swf is almost done “building” the layout, i have the actionscript load the content named “main” swf. When it starts loading the content, everything creeps to a crawl. All of the index animations and everything. I have loaders in place for the index, and for the content section.

Is this because I am “overloading” flash?

*When I removed the actionscript to load the main swf, everything runs smooth.

Any help would be really useful, as I want this site to work.
