It would be great to have an API or a command to tell you how many cycles out of max cycles are being used by a particular script, particular object, or by everything you own.
This would be very, very useful in determining if you have any bad scripts or objects that are slowing down or bogging down the sim.
Another way to do it might be an option in the Debug menu that gives you a display that shows max cycles on the sim CPU, shows all your objects and all the scripts on each object and how many cycles are being used per script per object and total.
Regardless a tool like this would be very useful in keeping sim speeds up and bad scripts out.
Perhaps even some kind of alert system where if you have a script or object that is using over some set number of cycles it would send you an IM or email alert with the offending object so you could do something about it.
