Yonik Seeley commented on SOLR-9822: ------------------------------------ Performance results of faceting on different fields... The 3 versions tested were: Solr from 09/09, Solr from 12/03, Solr from 12/03 + patch Solr from 09/09 is used as the baseline (old_time): || field cardinality || 12/03/2016 new_time / old_time || patch new_time/old_time || |10|1.52|0.97| |100|1.52|0.98| |1000|1.54|0.96| |10000|1.54|1.00| |100000|1.45|0.99| |1000000|1.16|0.99| Two takeaways: - the seekExact changes that Adrien introduced had a positive impact vs the initial results in SOLR-9599... the worst-case dropped from 2x slower to 1.5x - the patch in this issue fully restores the lost performance (plus a little due to an additional minor optimization) > Improve faceting performance with FieldCache > -------------------------------------------- > > Key: SOLR-9822 > URL: https://issues.apache.org/jira/browse/SOLR-9822 > Project: Solr > Issue Type: Sub-task > Security Level: Public(Default Security Level.
