setting isVisible=false is slow, reading display object x/y is slow

I don’t know if this is a bug or not, but i made a post here:

http://developer.anscamobile.com/forum/2010/11/13/performance-tip-setting-isvisiblefalse-slow-reading-display-object-xy-slow

I’m not really sure why setting the isVisible propery to false on a number of objects outside the screen would slow the app down from 30fps to 15fps (a lot of them will be invisible already as they are still offscreen from the previous frame)

Also reading their .y property is slow compared to for instance containing the graphic in an object table with a ypos parameter and reading that.

thanks for any feedback
