更新@2009/5/11:
Adobe 有個驅動Garbage Collection的方法:

flash.system.System.gc();
flash.system.System.gc();

但是必須連續呼叫兩次，第一次呼叫: 對物件加上記號；第二次：清除記憶體

在處理Grant Skinner發現的CPU效能問題之前，有幾個方法可以先改善AIR程式的效能:

1. 盡可能地減少frameRate
2. Grant Skinner提供了一個小程式，監聽 AIREvent.APPLICATION_DEACTIVE事件(該事件在AIR的native window失去focus時會觸發; 重新得到focus時，會觸發 APPLICATION_ACTIVE)，自動將frameRate降至 1 ,可以看他的文章: http://www.gskinner.com/blog/archives/2009/05/idle_cpu_usage.html
3. 盡可能用Timer; 而不是監聽EVENT.ENTER_FRAME做處理
4. 用profiler 查看Flex app吧
