Just thought I'd mention Jackson's blog. Here is a typical article: http://jacksondunstan.com/articles/810
I get a surprising amount of benefit in my Away3D work following his ideas to optimize Flash/Flex. The results are often surprising, for example, his odd little inline function that is a subtitute for "isNaN". If you use NaN to signify uninitialized numbers and test for them a lot, you'll be surprised at the savings. Not sure if Away3D itself has been optimized with these sorts of tips, but if not, it's worth looking into. Cheers, BW
