-------------------------------

Hi Alex, 

It's a real same that the problem isn't easy to solve. I think it's a very important performance
issue with a 20.000% worst performance and this reduce a lot the posibilities of the TLF.

Thank you so much for your work and time.

> I have a very strange performance difference between 2 versions of TextLayout.swc. The
first one is the swc included in Apache Flex 4.14 SDK and the second one is included in Apache
Flex 4.9.1. 
> I have a very large text, more or less 200 DIN-A4 pages in a Textflow. I scroll to the
end of the document and I underline a word. This is my result underling a word in both versions.

> Flex SDK Version     Time 
>    4.9.1                  21 ms (miliseconds). 0,02 Seconds 
>    4.14                   3.405 ms (miliseconds). 3,4 Seconds 
> The time difference happens in this line of code: 
> EditManager.applyLeafFormat(oFormat); 
> Anyone has any idea what's the problem?
