Karl, I'm not sure how to benchmark memory in AS 2. I think that what you
might want to benchmark here is cpu performance, anyway.
In this particular case, I don't think you can benchmark much, though.
Basically, all performance benchmarks I've seen are based on getTimer (two
simple calls to getTimer, one before running the code you're interested in,
and one after; the difference is very roughly how much your code took to
run; there are more sophisticated suites (like Grant Skinner's), but to my
knowledge, all are based on the same principle).
The problem here is that what seems to be taking too long is an internal
mechanism of the player (managing and dispatching onChanged, for instance).
Can't think of a way of timing that off the top of my head.
If one the methods runs your fan wild and the other one doesn't, though, you
have a clear winner already!
Cheers
Juan Pablo Califano
