macromedia players flash : Flash player CPU Usage

Does the flash player consume quite a lot of CPU usage even when there is no
events or actions happening? i have a application developed where there is no
ENTERFRAME, SETINTERVAL or Mouse LISTENERS, but still the CPU usage runs up to
70-80% i tried all sorts to cut this down but all my efforts are in vain.

This application builds a list of car details on a for loop nearly to 200+, i
understand at that point of time the CPU usage would go up but why is that
state maintained almost to 75%. Any thoughts on this?

The only thing I can seem to dig up that helped was lowering the frame rate
from 30 to 15. This cut back a bit. There are some other small optimization
tricks that slightly help but none of them seem to be a real solution.

There are a few articles which are out of date stating that flash player uses
100% of the available CPU until it is called on by another application. I did
some tests with applications running and a flash website running in a browser
and as I quit the applications the browser did start to take up more CPU. It
seems like there is some truth in this.

When I download the Flash Player 8 & 9 security.pdf it goes into saying that
Flash player has now created quotas on what the amount of memory and CPU it
will use. So that negated this thought.

So basically I came up with a whole lot of nothing. It is exceptionally hard
to test this stuff and the effect it will have on peoples computers in a live
environment with no documentation or answers to this.

IF ANYONE has an answer to this it would be greatly appreciated.
