[flexcoders] AS 3 performance articles?

[joshuajnoble]

Hi,
I need some whitepapers/articles/blog posts/whatever, on AS3 display
performance  vs AS2 (for a client) and especially, if possible, info
on why you should use AS3 event handling or info on event handling in
as3. I've been googling around and have found some stuff, but not
everything. Anyone know where more stuff is? In particular, what
happened to that PDF on as3 performance tuning from Gary Grossman (the
one that his talk at Max was based on)?
