I enabled LTR feature extraction and response times spiked. I suppose that was to be expected, but are there any tips regarding performance? I have the feature values cache set up as described in the docs:
<cache name="QUERY_DOC_FV" class="solr.search.LRUCache" size="4096" initialSize="2048" autowarmCount="4096" regenerator="solr.search.NoOpRegenerator" /> Do I simply have to wait for the cache to fill up and hope that response times go down? Should I make these cache values bigger? * Brian
