Summary: Solr LTR tree model latency optimisation
Key: SOLR-15314
URL: https://issues.apache.org/jira/browse/SOLR-15314
Project: Solr
Issue Type: Task
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Suryakant Pandey
Currently, tree traversal for solr LTR model happens in a recursive manner.
This came out to be a performance bottleneck( via solr profiling) in terms of
solr latency when we tried to increase number of trees.
(Recursion is slower due to overhead of function call stack)
We optimised this by translating recursion logic to loop based approach.
