I have been using the compressor and decompressor for a while now. One of the issues is the performance not sufficient for large data operations. The underlying zlib library is single-threaded, and there is a parallel version implementation at application level https://zlib.net/pigz/ pigz. When working with large file compression and decompression it usually take 8 hours to do the job. If I can use multi-threaded version then it usually can be done within one hour. There is a strong need to use multi-threading to speed up this process for me. I would appreciate that someone can implement this feature. If not I can work on this project. Not sure what's the best way to go about this. -- Kemin Zhou 858 366 8260
