Does there exist somewhere a reference that says approximately how expensive (in terms of CPU usage) various functions/operations are in Actionscript?

For example, how expensive is applying a blurfilter of default quality to a 100x100 bitmapData versus, say, applying a colorTransorm? Is it twice as expensive? Ten times?

I’m not looking for an answer to this specific example, but just if anyone has compiled even a partial reference on Actionscript 3 function performance.
