Subject [jira] [Commented] (FLEX-33865) ConstraintLayout / LayoutElementHelper are memory inefficient (and slow)
Date Mon, 04 Nov 2013 02:32:18 GMT

Justin Mclean commented on FLEX-33865:
--------------------------------------

The largest benefit come from removal of the regexp, perhaps it would of better to break this
