Using static variables and functions is slow. That was the conclusion of the previous article on statics, but the subject is actually more nuanced than that. Today we’ll explore static more in-depth and find out just why it is so slow.

Along with Flash Player 11’s new
Stage3D class have come hardware-accelerated 2D rendering engines. Impressive results have already been demonstrated by advanced engines like Starling and ND2D. Today’s article shows a simple
Stage3D-based sprite class to help learn more about how these engines are implemented and provides a simplified alternative to the more complex 2D engines that still delivers hardware-accelerated performance.
One of the new features in Flash Player 11 is a native JSON encoder/decoder class. In the Serialize Anything article, I neglected to add JSON as an option for serializing and deserializing arbitrary objects. In today’s followup we’ll take a look at the performance of the native JSON class and compare it to
ByteArray.readObject/writeObject and XML.
Tip #8 in my Top 10 Performance Tips For 2012 was to reduce static accesses of variables, functions, etc. in favor of non-static variables and, especially, local variables. I neglected to reference one of my articles and it was pointed out to me that I hadn’t actually written such an article! So today I’ll elaborate on my tip and show why you should prefer non-static and local variables so you can find out just why it deserves its place as a top tip.
