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 (
5M document index, 21 segments, single valued string fields w/ no missing values.
|field cardinality||new_time / old_time|
So unfortunately, often twice as slow.
See followup messages for tests using real docvalues as well.
