Subject [jira] [Commented] (FLEX-34769) TLF Performance issue (applyLeafFormat method)
Date Mon, 07 Dec 2015 17:06:11 GMT

    [ https://issues.apache.org/jira/browse/FLEX-34769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15045250#comment-15045250

Alex Harui commented on FLEX-34769:
-----------------------------------

Makes sense.  I'm wondering what, if anything, will break by taking that out, which is why
I had put a flag around it in change 592b45fa219af46592f30ad712b739ac606ed296.  Something
Adobe added since the 3.0 branch probably caused someone to add that line as a workaround.
 And then it appears that something in your table work required the removal of the flag, or
was that just a merge thing?  Maybe we have enough tests to find out.  Otherwise, I would
advise putting back the flag so folks can have a choice if someone find out why that workaround
was added after we release.

> 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?
