Alex Harui updated FLEX-34247:

    Attachment: log4.txt

I am able to paste the attach file in both 4.6 and 4.12.1 in the same amount of time.  It
takes a long time, but I am not seeing a difference.

>          Components: Spark: TextArea
>    Affects Versions: Apache Flex 4.12.0
>         Environment: Win 7 64 Bit, FP 13

> 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 :(
