Anecdotal evidence that useFilterForSortedQuery has gotten much slower in 3.5 compared to 1.4 ---------------------------------------------------------------------------------------------
Key: SOLR-2944 URL: https://issues.apache.org/jira/browse/SOLR-2944 Project: Solr Issue Type: Bug Reporter: Hoss Man Pawel Rog reported on the user list that he was seeing significantly slower search performance and much higher CPU usage using Solr 3.5 compared to Solr 1.4 when using the same configs he had always used in Solr 1.4 -- even though he had a new index built with 3.5 https://mail-archives.apache.org/mod_mbox/lucene-solr-user/201111.mbox/%3ccaf9zkbpho0y-pvskm4dkanc7aargacfsshnqbl+noot1ahx...@mail.gmail.com%3E Based on stacktraces from threaddumps the "useFilterForSortedQuery" was determined to be a contributing factor, and disabling it improved performance (exact comparison not provided). Would be nice to get some more details and a reproducible comparison (SOLR-2646 where are you???) and evluate why useFilterForSortedQuery would be slower in 3.5 then in 1.4 with the same data. Should consider actively removing the useFilterForSortedQuery=true option if there are no longer any usecases where it's better then useFilterForSortedQuery=false -- This message is automatically generated by JIRA.
