Hi Alex,

- The application is 6778 .as and 10315 .mxml (some of the .as are visual
components and optimized as noted in your document)
- The migration is from 3.6 to 4.8
- I migrated from mxml 2006 to 2009 as much as I could, only modules,
components which contains States are still in mxml 2006
- Almost all the styles are in .css
- Each functional part of the application is benchmarked.
- I ran both version (flex 3 / 4) on the same computer, with the same data
loaded, at the same time and with FP 11.4

The Flex 4 version was in compatibility mode because otherwise, with spark,
I found much more gap between both versions.

The result is: 
I found a gap of 35% between flex 3 / 4 ( Flex 3 compatibility mode) for the
richest screens, 20% more or less for the others.

Are you doing dynamic add of display objects?  If so, the latter part of
that article might pertain to you.

Otherwise, please provide more information on your scenario and what changed
going from 3 to 4.  Which version of 4?
