More info on ActionScript Optimizations in Beta Player

There have a been a couple of questions about what parts of ActionScript have been optimized in the new player. I talked to the Flash Player team and they passed the following info to me:
Movies which make lots of function calls (something recursive, such as a QuickSort algorithm on an array of 10,000 items) will be faster (provided they don’t access the arguments array).
If anyone gets some benchmarks together, make sure to post a  link to them in the comments.
