Question

I need to store a lot of data coming in from a server into memory, so I have to write my memory-storage algorithms based on how much I can safely use without hanging up or crashing the browser.

Is there any safe size limit like 1MB or 100MB, that contents of global variables should not exceed?

Answer 1

You can check how much memory you are using with:

trace("MEMORY USAGE: " + (System.totalMemory/1048576) + "MB");

Use this to help keep locate memory leaks and to improve your garbage collection code.

In actionScript 2 they say you should both clear and delete dynamically created objects for quickest GC.

myArray[0] = "value";

myArray[0] = null; // to Garbage Collect
delete myArray[0];
