[jira] [Comment Edited] (SOLR-9822) Improve faceting performance
with FieldCache
[ https://issues.apache.org/jira/browse/SOLR-9822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15718886#comment-15718886 ]

--------------------------------------------------------------
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 advanceExact 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)
