The recently released zlib addon is a big plus for j64 users. The compiled version is very effective on J text and might prove useful for binary data as well.
The following is a worst case scenario - compressing and uncompressing a million random numbers t =. 1000000?1000000 ts' t -: (3!:2) zlib_uncompress zlib_compress (3!:1) t' 0.987848 3.77554e7 But on my 64 bit win8.1 machine it gets through the cycle in less than a second. On more realistic data performance is much better. Kudos to Bill and anyone else that worked on this addon. -- John D.
