Subject [jira] [Commented] (FLEX-34769) TLF Performance issue (applyLeafFormat method)
Date Mon, 07 Dec 2015 19:04:11 GMT

    [ https://issues.apache.org/jira/browse/FLEX-34769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15045505#comment-15045505

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

I'm not sure how I missed it in the merge.

IIRC, the unit tests were not working at all until after I committed the table code, so I
doubt the tests were run before the merge. I guess we could roll back to a version of the
code before that and run the tests on that to see, but I'm going to see why the tests are
currently failing so spectacularly. I'm currently getting 33 errors before the tests crash
at about the 200 mark.

> 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?
