I am gonna be blunt and say I am quite annoyed that you did not read my post at all. 85 ms is a 1600% increase in lag, the first time the state changes. This is also a scaled down version of the problem with only a SINGLE component. The more components you add, the worse the delay gets.
After spending a lot of time searching, this seems to be a bug that has existed for quite some time as early as Flex 4.1. https://bugs.adobe.com/jira/browse/SDK-30302. Now in flex 4.6, it is still broken with the 9 month old bug report closed and deferred
itemCreationPolicy and creationPolicy do not work at all in conjuction with includeIn/excludeIn. At least the work-around kind of works, although I am sure there are plenty of people still using the creationPolicies not knowing why their applications are so slow.
It is quite true that I am going really fast reading through posts so I can certainly not understand the issue, so I apologize. I did notice you had creationPolicy=”all” which is not a recommended practice. If you are concerned about performance I would not use creationPolicy=”all” and fix the issues caused by changing that.
