Otis Gospodnetic commented on LUCENE-1219:
------------------------------------------

Eks Dev: out of curiosity, did you ever measure the before/after performance difference? 
If so, what numbers did you see?

> currently Field/Fieldable interface supports only compact, zero based byte arrays. This
forces end users to create and copy content of new objects before passing them to Lucene as
such fields are often of variable size. Depending on use case, this can bring far from negligible
 performance  improvement. 
> this approach extends Fieldable interface with 3 new methods   
> getOffset(); gettLenght(); and getBinaryValue() (this only returns reference to the array)
