Hi, I test facets and stats in Solr 3.5 and I see that queries are running a lot slower during inserts into index with more than 15M documents . If I stop to insert new documents facet/stats queries run 10-1000 times faster than with concurrent inserts. I don't see this degradation in Lucene.
Could you please explain what may cause this? Is it Solr related issue only? Thank you for help. Best regards, Lyuba
