我也在寻找AS的分析器，但是我想要一个可以与FlashDevelop和Flex SDK一起使用的免费软件/开源解决方案。我没有找到。所以我写了一个简单的python脚本和一个更简单的AS类。该脚本基本上采用任何AS文件，并添加了分析代码(即调用以测量该功能的总运行时间，精度为1 ms，即flash.utils.getTimer()调用的分辨率)到每个函数定义。脚本有时候会出错，但这些脚本通常很容易用手修复。然后，您需要手动添加一行：在某一时刻将分析统计信息转储到某处。这种方法显然远不是准确的，但是它给你的代码带来了瓶颈的良好感觉。我用它成功的一个100k文件。

这是AS类：

package  {
    public class Profiler {
        private static var instance:Profiler;

        public static function get profiler():Profiler {
            if (!Profiler.instance) Profiler.instance = new Profiler;
            return Profiler.instance;
        }

        private var data:Object = {};

        public function profile(fn:String,dur:int):void {
            if (!data.hasOwnProperty(fn)) data[fn] = new Number(0);
            data[fn] += dur / 1000.0;
        }

        public function clear():void {
            data = { };
        }

        public function get stats():String {
            var st:String = "";
            for (var fn:String in data) {
                st += fn + ":\t" + data[fn] + "\n";
            }
            return st;
        }
    }
}

这里是python脚本的诀窍：

rePOI = sre.compile(r'''\bclass\b|\bfunction\b|\breturn\b|["'/{}]''')

    match = rePOI.search(body,pos)
    while match:
        poi = match.group(0)
        pos = match.start(0)

        if poi in '''"'/''':
            strm = reStr.match(body,pos)
            if strm and (poi != '/' or sre.search('[=(,]\s*$',body[:pos])):

        elif poi == 'class':

            if sre.match('return\s*;',body[pos:]):
                line = "{ Profiler.profiler.profile('" + lastf['name'] + \
                       "',flash.utils.getTimer() - __start__); return; }"
            else:

            body = body[:pos] + line + body[semicolon:]
            endpos = pos + len(line)

        elif poi == '}':
            depth -= 1
            if len(stack) > 0 and stack[-1]['depth'] == depth:
                lastf = stack.pop()
                line = "Profiler.profiler.profile('" + lastf['name'] + \
                    "',flash.utils.getTimer() - __start__);\n"
                body = body[:pos] + line + body[pos:]
                endpos += len(line)

        pos = endpos
        match = rePOI.search(body,pos)
    return body
