Paul Elschot commented on LUCENE-2232:
--------------------------------------
Aside: the patch has an unrolled version of IndexInput.getVShortInt() into 3
explicit getShort()'s.
Has it been tried to unroll getVInt()? Unrolling getVInt into 5 explicit
getByte()'s has the advantage
that the later conditional jumps are easier to predict.
> Use VShort to encode positions
