Adrien Grand commented on LUCENE-2750:
--------------------------------------
For the record, Daniel Lemire wrote a post about PFOR delta decompression speed
at http://lemire.me/blog/archives/2013/07/08/fast-integer-compression-in-java/.
I have not dug the reasons that may explain why his implementation is faster
than kamikaze or if the benchmark itself is relevant to Lucene but I think it's
something worth looking into.
> add Kamikaze 3.0.1 into Lucene

> Kamikaze 3.0.1 is the updated version of Kamikaze 2.0.0. It can achieve
> significantly better performance then Kamikaze 2.0.0 in terms of both
> compressed size and decompression speed. The main difference between the two
> versions is Kamikaze 3.0.x uses the much more efficient implementation of the
> PForDelta compression algorithm. My goal is to integrate the highly efficient
> PForDelta implementation into Lucene Codec.
