    • Added New compression levels for GzipCodec that can be set in zlib.compress.level

    Description

      gzip supports compression levels 1-9. Compression level 4 seems to give best compression per CPU time in some of our tests. Right now ZlibCompressor that is used by GzipCodec only supports levels 1,9 and six (default).

      Adding all the compression levels that are supported by native ZlibCompressor
      can provide more options to tweak compression levels.
