Above all others, there is one article I refer back to most: 2009′s Function Performance. It was updated for Flash Player 10.1 and 10.2, but not 10.3, 11.0, 11.1, or 11.2. Today I’m updating this article for Flash Player 11.2, adding some missing function types, and including a set of graphs to make for the ultimate function performance reference.

I recently perused the AVM2 bytecode overview that Adobe provides and found something strange: they have special instructions for the first few local variables. Getting the first local variables is done by getlocal0, getlocal1, getlocal2, getlocal3, but then a generalized getlocal is used for local variables thereafter. This brought me to think about the performance implications of these specialized instructions. After all, why have them when you already have a generalized one? Read on to see the performance differences and if you can get any speed boost from rearranging your local variables.
