Adrien Grand commented on LUCENE-6024:
--------------------------------------
The impact of this change is also noticeable on the charts:
http://people.apache.org/~jpountz/doc_id_sets6.html the sparse set is now
always almost as fast to build from another DocIdSet as a FixedBitSet.
> Improve oal.util.BitSet's bulk and/or/and_not

> LUCENE-6021 introduced oal.util.BitSet with default impls taken from
> FixedBitSet. However, these default impls could be more efficient (and eg.
> perform an actual leap frog for AND and AND_NOT).
> Additionally, SparseFixedBitSet could benefit from some specialization.
