Re: FLASH: Speed vs. Size (was:getting a bit confused !)

>But you overstate the effect of Nesting on processor speed.


Just to add my two cents from a programming standpoint (and from the

standpoint of someone who is actually implementing a Flash player):


Each movie clip is executed independently of the current timeline as a

separate thread. While this thread management can bog down in some

situations, it is far more efficient in most. With a competent 32-bit

operating system (WinNT4 and now Linux, don't know about MacOS8.5) and

multiple processors, the movie clips can actually be more efficient with

tweening because the threads will be off-loaded to an alternate processor.

While this won't necessarily speed up the graphics rendering (alpha and

gradients), it will speed the tweening (shape morphing, scaling) computations.


For the greater majority of animations, this is a mute point. The largest

bottle neck of vector graphics processing are the gradients and alpha

(which includes anti-aliasing), two things that are unaffected by movie clips.
