Re: Performance issue with nested iterator
I believe I've found the culprit. While the problem is present in commit https://github.com/mmalmeida/struts-performance/commit/aba93098174c8c8c1684ffdd9bf332b212a893a , it's not present in the latest commit if you turn devMode to false. The issue was the freemarker version 2.3.9 in that commit. Updating to 2.3.19 makes performance normal again (the complete project needed freemarker, hence the direct dependency reference in the pom). While I don't know what changed between these freemarker versions, apparently the problem was there.

Re: Performance issue with nested iterator
Sorry, I sent the email before explaining. The repo has a maven project that I stripped down to the most basic to show the issue. Notice the iterator in index.jsp. I tried to remove every unused configuration, file and dependency to make the project as simple as possible. The original project is using tiles, so I kept it there. However, I don't think it's being used in the web workflow I created (which just goes to index.jsp). Is there anything there that might explain this slowness?

Re: Performance issue with nested iterator
Could you post somewhere (GitHub) the whole code base ? Regards -- Łukasz + 48 606 323 122 http://www.lenart.org.pl/ - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Performance issue with nested iterator
Dear all,
I have got a performance issue on a nested iterator, running Struts
2.3.1.1.
Consider the code below, (the example is a Book with chapters and
subchapters and we're displaying the book index - bookIndex is a
Map>.
This takes several seconds to load (map has size 10, each list is no
more than 15 items). I tried a lot of different approaches (mainly
regarding the database). However, what really surprised me was the
contents of the innermost (6th row from the end): if I replace the
with anything else (a xx, or just an xx) the page will load
much faster (ie, page load drops from 8 to 2 seconds).
Looking at http://struts.apache.org/2.x/docs/performance-tuning.html, I
double checked the OGNL version loaded in maven and indeed I have 3.0.3.
Is there any obvious reason why I'm getting such a slow performance?
Thanks for the input!
Miguel Almeida
Example code:
${chapter.firstPage}
${chapter.name}
