Using System.totalMemory to analyze flash memory usage
When looking for memory leaks on an application that loads many bitmaps, Internet Explorer showed much lower memory usage from System.totalMemory than FireFox. The difference is because
not everything allocated in the player is allocated by the internal allocator, nor reported through totalMemory…namely anything allocated by OS system calls, memory associated with platform bitmap data, and the JIT buffer associated with the Actionscript VM.”
