Solr upgrade|| LTR performance degrade

Hi All,

We have recently upgraded the solr from 8.2.0 to 8.8.2. During the
performance testing it was observed that Response time for the LTR is
degraded by 35%.

LTR Implementation details:
Model class : MultipleAdditiveTreesModel

Out of the box classes are used for the implementation, we are unable to
pin point what is causing the degradation as it is internal to solr.

Is there a configuration that needs to be taken care ? any ponter regarding
this wil be. of great help

-- 
Regards,
Sachin

Re: Solr upgrade|| LTR performance degrade

Posted by Anna Ruggero <a....@sease.io>.
Hi Sachin,
I executed the same set of learning to rank queries (50 queries) with and
without feature extraction on the same Solr collection and on three
different Solr versions: 8.2, 8.7, and 8.8.
Here are the obtained results:

Since I cannot reproduce the degradation you are referring to, could you
give me some further information about the schema, documents,
models/features, and queries you are using?
It would really help.

Thank you,

Re: Solr upgrade|| LTR performance degrade

Posted by Alessandro Benedetti <a....@sease.io>.
So you noticed that the degradation was also there pre 8.8 (<8.8)?
Have you identified the first version having the regression?
Was it there with 8.7, this information would help a lot!

Hi Alessandro,

Sorry Missed the mail , the degradation continued to exist with various
higher versions. So we dropped the upgrade idea as we are in 8.2 version
solr.

Hi Sachin,
We didn't get any update on this.
As an Apache Solr committer, I deeply care to provide the best software
possible to our users.
As a user, you can do your part in helping us understand possible bugs and
regressions.
Let us know and we can try to identify the regression and fix it!

Re: Solr upgrade|| LTR performance degrade

Hi Sachin,
can you try also Solr 8.7 and Solr 8.8?
In 8.8 has been introduced new functionality in LTR which is Interleaving.
It shouldn't affect performance though, so we need to understand when the
regression happened, to fix it.
Your help is much appreciated,
Cheers
