Hi, I made change in the model by making the LTRScoringModel as immutable and cache hashCode calculation. The response time improved a lot after the change. http://lucene.472066.n3.nabble.com/jira-Updated-SOLR-12688-LTR-Multiple-performance-fixes-pure-DocValues-support-for-FieldValueFeature-td440

It is a little bit difficult to say, because it could be also the business logic in the query execution. What is your performance baseline, ie if you just execute one query for each of the models? How fast should it be? Do you have really 10 or more concurrent users, or users that fire up querie

Hi, Any update on this? Is this model running in multi threaded mode or is there is any scope to do this. Please let me know. Regards Kamal On Sat, Mar 23, 2019 at 10:35 AM Kamal Kishore Aggarwal < kkroyal@gmail.com> wrote: > HI Jörn Franke, > > Thanks for the quick reply. > > I have perfor

HI Jörn Franke, Thanks for the quick reply. I have performed the jmeter load testing on one of the server for Linear vs Multipleadditive tree model. We are using lucidworks fusion. There is some business logic in the query pipeline followed by main solr ltr query. This is the total time taken by

Can you share the time needed of the two models? How many documents? What is your loading pipeline? Have you observed cpu/memory? > Am 22.03.2019 um 12:01 schrieb Kamal Kishore Aggarwal : > > Hi, > > I am trying to use LTR with solr 6.6.2.There are different types of model > like Linear Model,

Hi, I am trying to use LTR with solr 6.6.2.There are different types of model like Linear Model, Multiple Additive Trees Model and Neural Network Model. I have tried using Linear & Multiadditive model and compared the performance of results. There is a major difference in response time between th
