Adrien Grand commented on LUCENE-4598:
--------------------------------------

Nice that PayloadIterator now returns a direct reference to payloads instead of copying data!

> Currently the facet module uses MultiFields.* to pull the D&PEnum in PayloadIterator,
to access the payloads that store the facet ords.
> It then makes heavy use of .advance and .getPayload to visit all docIDs in the result
set.
> I think we should get some speedup if we go segment by segment instead ...
