Yonik Seeley updated SOLR-9599:
-------------------------------
Description:
I did a quick performance comparison of faceting indexed fields (i.e. docvalues
are not stored) using method=dv before and after the new docvalues iterator
went in (LUCENE-7407).
5M document index, 21 segments, single valued string fields w/ no missing
values.
|| field cardinality || new_time / old_time ||
|10|2.01|
|1000|2.02|
|10000|1.85|
|100000|1.56|
|1000000|1.31|
So unfortunately, often twice as slow.
See followup messages for tests using real docvalues as well.
