Subject [jira] [Commented] (FLEX-34769) TLF Performance issue (applyLeafFormat method)
Date Mon, 07 Dec 2015 18:02:11 GMT

    [ https://issues.apache.org/jira/browse/FLEX-34769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15045358#comment-15045358
] 

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

In theory, Git merge should have preserved my flag.  Did you run into conflicts?

AIUI, before you merged in the table work, TLF was working fine without needing to reset to
0, but I don't know if we ever ran the current tests against any pre-Table TLF.  So that could
imply that any RTEs in the current tests show some reliance on reset to 0 which might shed
light on what the issue was that caused that workaround to go into the code.

Good luck.

> 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?
