Robert Muir updated LUCENE-5643:
--------------------------------
Attachment: LUCENE-5643.patch
In my benchmark, the performance differences for indexing was very minor with
this patch. So i want to put it on the backburner. Seems there are other things
to fix first (times in milliseconds):

> Followup from LUCENE-5638: NumericTokenStream has its own factory, wrapping
> AttributeFactory.DEFAULT_ATTRIBUTE_FACTORY.
> Currently it gets no speedup from the change, but I think it could (I saw
> speedups for even StringField from that change)
> It has 3 attributes: NumericTermAttribute, posIncr, and type. Maybe the
> NumericTermAttributeImpl should also implement posIncr and type?
