If you were to put your whole project in one loop and at the very end put in the "change frame rate by 1" then use the scripts I've created or similar, it would tell you how fast your project was running. this only really works for 1 sprite 1 script project. which I tend to make a lot of. in my scratched version of impossible game I've implemented this frame rate counter. -- it averages the number of times it goes through the loop per a second which is the number of frames. -- after a while the counter stablizes -- try switching between the java player and the flash player and seeing the differences in speed. you can also try switching between the development mode and presentation mode offline.
