> I run into performance issues with TextArea with Apache Flex 4.12.
> After pasting a text of approx. 400000 chars into TextArea, it freezes for some time but becomes responsive again. Then I noticed the follwing:
> In Flex 4.6: I can enter chars into TextArea at any speed without any problems.
> In 4.12: the FlashPlayer freezes on each char entered for some time, rendering TextArea for long texts unsable. 
> I know there is much effort in TLF, but this feels like a downgrade, because handling huge texts in a very fast way was my reason to choose TLF, but this was about 2 years ago.
> Do I now have to stay on tlf 1.0 for handling huge texts? Would be sad :(
