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

             Summary: Performance with TextArea using TLF 
                 Key: FLEX-34247
                 URL: https://issues.apache.org/jira/browse/FLEX-34247
             Project: Apache Flex
          Issue Type: Bug
          Components: Spark: TextArea
    Affects Versions: Apache Flex 4.12.0
         Environment: Win 7 64 Bit, FP 13
            Reporter: Benjamin Ludwig


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 :(

regards
benny
