Trunk ecommerce main screen 4 times slower then 1.5 year ago.

[hans_bakker]

currently we are helping a customer to upgrade their ofbiz version.
We are using "Apache bench" to test the ecommerce frontend.

We now found that the current trunk is dramatically slower than rev
728596 from about 1.5 years ago.

the test results:
rev 728596:
total time : 34.667 seconds
Requests per second:    14.42 [#/sec]

trunk rev 959845
total time : 152.698 seconds
Requests per second:    3.27 [#/sec]

below the complete test results.

Help appreciated.

Regards,
Hans.

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.

Hi Hans,

If you have time it would be great if you could try out some of the versions between 2.3.10 and 2.3.15 in order to help pin down exactly which release is giving us trouble.  If we know which one it is then the problematic changes will be much easier to track down.

Regards
Scott

   - For Version 2.3.14, I have to check null value before call
   DeepUnwrap.unwrap() method in CatalogUrlDirective.java. And got " Time taken
   for tests: 176.806 seconds".
   - For Version 2.3.13, I have to check null value before call
   DeepUnwrap.unwrap() method in CatalogUrlDirective.java. And got " Time taken
   for tests: 96.021 :  seconds".
   - For Version 2.3.12 and 2.3.11, Can not compile

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.

[Jacopo Cappellato-4]

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

Hey Jacopo.   It looks as though the improvement in performance is due
mainly to a logging parameter change.  However, the original post indicated
a 4x performance deficit, which isn't really reflected in the below
statistics.

It's faster, but nowhere near 4x.  Is it possible to downgrade freemarker
to gain back performance?

Hi Jacopo,

it is just a single commit: r986577

lets first wait until that is fixed?

Hans
