Thank you Hans,
I had to actually spend a lot of time to fix it.
But at the end it was not an issue in Freemarker but instead the problem was that we were not disabling debug messages in
freemarker classes.
I have fixed this by adding proper Log4J configuration and then I have upgraded to the latest stable release of freemarker
(2.3.19).
The performance looks good; I have executed (using JMeter) the main ecommerce screen with 50 threads hitting the page 100 times
each:
with 2.3.10
Generate Summary Results = 5000 in 195.2s = 25.6/s Avg: 1925 Min: 74
Max: 9307 Err: 0 (0.00%)
with 2.3.19
Generate Summary Results = 5000 in 187.6s = 26.6/s Avg: 1842 Min: 88
Max: 8483 Err: 0 (0.00%)
The new version is slightly faster now.
Hans, could you now please revert the changes you did when you switched back to 2.3.10? I am especially interested in having back
the catalog Directive (instead of the Transform) because in future versions of Freemarker Transforms will not be supported and we
will have to start the migration to directives: having one in place will definitely help.
Thanks,
Jacopo

An update on this: I have found and resolved the issue that Hans reported on
Freemarker bug tracker:
https://sourceforge.net/tracker/index.php?func=detail&aid=3046069&group_id=794&atid=100794
Now I am working with them to see if my change can be made official and
released.

I found only that
http://freemarker.sourceforge.net/docs/app_faq.html#faq_question_25 So nothing
special.
We could try to upgrade to newer versions but 2.3.16 does not seem to bring
much and 2.4 is not ready yet.

We are using "Apache bench" to test the ecommerce frontend.
We now found that the current trunk is dramatically slower than rev
