Subject [jira] [Commented] (FLEX-34769) TLF Performance issue (applyLeafFormat method)
Date Wed, 09 Dec 2015 22:05:11 GMT

Harbs commented on FLEX-34769:
------------------------------

I think I fixed it! Phew! The fix was pretty simple, but it took my more than two long days
just to find the problem...

FlowComposerBase.addLine() was not the problem. It was a symptom. It turns out the start line
location was not being synced up correctly when composition started in middle of a paragraph.

I ran all tests successfully. I still need to run the performance test, but I need to clean
up my code and get rid of all the traces I put in to find the problem.

> 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?
