Hi：
When I use LTR, there are 72 features, 500 models and 200 million data.
During use, LTR execution was found to be extremely slow, with each query above
5s.
Through the analysis found in LTRScoringQuery ModelWeight scorer method
of class 72 when creating FeatureScorer feature value in the use of content of
the slowly, and here is the synchronization of execution.
I tried to change this to multithreaded, which had some effect. The
average query time was 600ms.
Is it too slow for payload or is there room for optimization here?
thank you
