There seems to be some anecdotal evidence that it runs very slowly and we are seeing some eveidence of this. How can others see this too? A link to a particular SWF would be fine, but more direct would be a description of how others could make a small file to test a particular function. If other people can see it too, then we can make some progress. Generally, new Players must play old content at least as well. There are some particular features which may not follow this rule (security requirements are one prominent exception), but the public Developer Releases are for identifying and addressing any such degradations.

Re: [Flashcoders] Slow performance of Flash 7 content in Flash Player9
In general, swf7 content should be the same or faster in FP8/9 than in FP7. AVM2 is completely separate from AVM1, but some aspects are shared. For example the incremental garbage collector, which was introduced in FP8. It's *possible* that certain apps on certain systems might appear to run slower, because of how they consume memory and how that affects the GC, but this would apply to FP8 as well as 9. Strings are stored and managed differently in AVM2, and I'm not sure if that code change is shared with AVM1.

That's a very good point to bring up- since you are only revealing a
big block of text without extra effects, you could just use a mask.

If you're looking to improve performance and keep the speed of your
animation, you could experiment with BitmapData.draw() and render a bitmap
copy of a hidden text movieclip. I think the bottleneck is mostly due to
the heavy font vectors. If your font movieclip was hidden and/or moved
off-stage, you could probably get away with a single BitmapData object set
to the size of the screen, redrawing each time the text changes.

RE: [Flashcoders] Slow performance
Thanks for the replies so far...
I am now using BitmapData.draw() ( and source_mc._visible=false + moved
offstage ): it run a little faster than before. And only seems to choke when
the browser is maximized at higher resolution ( around 1280x1024 ), maybe I
am knit picking?...
But, I think something is not going right in my code and that the draw loop
could be optimized. The code now looks something like this:
// code
private function animationLoop( ):Void{
if ( lineCounter > code_lines.length ) lineCounter = 2
if ( lineCounter == 0 ) {
field_txt.text = code_lines[lineCounter]
} else { field_txt.text = field_txt.text +
code_lines[lineCounter] }
myBitmapData = new BitmapData(source_mc._width,
source_mc._height , false, 0x );
target_mc.attachBitmap(myBitmapData, 10);
myBitmapData.draw(source_mc);
lineCounter ++
}
// code
I am finding it a little odd, that I am making a new BitMapData object every
interval and tried moving it outside the loop but got strange results (due
to my ignorance): every time 'attachBitmap' ran, it seemed the old bitmap
was not being cleared.
+ also changed the font to Verdana, tried various interval times, but
neither of these did much to improve the situation. Anyone think I can
squeeze a little more FPS out of this one?..

If you're looking to improve performance and keep the speed of your
animation, you could experiment with BitmapData.draw() and render a bitmap
copy of a hidden text movieclip. I think the bottleneck is mostly due to
the heavy font vectors. If your font movieclip was hidden and/or moved
off-stage, you could probably get away with a single BitmapData object set
to the size of the screen, redrawing each time the text changes.

RE: [Flashcoders] Slow performance
pushing things to 10ms seemed to work best. I will try experiment with
BitmapData. I hope that will do the trick.
Thanks

I'm seeing a window full of text (Firefox, Win XP Pro) -- is this
