ActionScript 2的VS ActionScript 3的性能 [英] ActionScript 2 vs ActionScript 3 performance
问题描述
所有的标准整数，数组，函数，类等，性能在这2种语言（编译器）？
Any benchmarks of Integer, Array, Function, Class, etc, performance in these 2 languages (compilers)?
比较也将是有益的。
推荐答案
由于AS3在不同的虚拟机（AVM2）比AS2（AVM）也已显著的性能改进与引进AS3的运行。一般情况下，由AVM2执行的运算code运行约10倍比老AVM类似的运算code的运行速度更快。当然，这并不意味着一切都在AS3是比AS2快10倍的倍。随着引进AS3的所有的显示的功能，或所有典型的闪存API的，还没有在速度仅逻辑和code执行处理的算术部分增加。例如。应用模糊滤镜上的视觉元素一样快与AS2，因为它与AS3然而，这样做3D转换的速度要快得多用AS3。 AS3还介绍了一些新的数据类型，可以提高性能，以及（所有尽管这并不一定总是这种情况）。
Since AS3 runs in a different virtual machine (AVM2) than AS2 (AVM) there have been made significant performance improvements with the introduction of AS3. In general, opcode executed by AVM2 runs about 10x faster than similar opcode running in the old AVM. This of course does not mean that everything in AS3 is 10x times faster than with AS2. With the introduction of AS3 all the display functions, or all the typical Flash API's, haven't increased in speed only the logic and arithmetic part of the code execution process. E.g. applying a blur filter on a visual element is just as fast with AS2 as it is with AS3 however, doing 3D transformations is much faster with AS3. AS3 introduces also some new data types which can increase performance as well (all though that doesn't necessarily always be the case).
