--------------------------------

    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?
