This is what I use:

[AS]  
Object.prototype.getFPS = function() {  
if(signal == true) {  
time = getTimer();  
} else {  
rate = int(1000 / (getTimer() - time));  
}  
signal = !signal;  
return rate;  
}  
[/AS]

and to have it be displayed, set up a dynamic text field on the stage somewhere, and:

[AS]  
text\_field.text = "FPS: " + getFPS();  
[/AS]

This code is slightly inaccurate but it works if you want to detect slowdown:

onClipEvent (enterFrame) {  
t = getTimer();  
framerate = Math.round(1000/(t-o));  
o = t;  
}

framerate is your framerate (obviously)

\*note: those three lines in the clipEveent MUST be in that order.

wow thank you all very much for your help wonderful 🙂 I plan on recording data and in order to eliminate outliers I have to throw out data on computers that the fps fell below a certain point 🙂

Thanks again very much 🙂
