  • Why I enjoy using the Nim programming language at Reddit.

    Another example of Nim being really fast is the supersnappy library. This library benchmarks faster than Google’s C or C++ Snappy implementation.

    It doesn't destroy performance for the simple reason that nowadays memory access has higher latency than pure compute. If you need to use compute to produce some data to be stored in memory, your overall throughput could very well be faster than without compression.

    There have been a large amount of innovation on fast compression in recent years. Traditional compression tools like gzip or xz are geared towards higher compression ratio, but memory compression tends to favor speed. Check out those algorithms:

    * lz4: https://lz4.github.io/lz4/

    * Google's snappy: https://github.com/google/snappy

    * Facebook's zstd in fast mode: http://facebook.github.io/zstd/#benchmarks

  • Compression with best ratio and fast decompression
    1 project | /r/learnprogramming | 30 Aug 2022
    Google released Snappy, which is extremely fast and robust (both at compression and decompression), but it's definitely not nearly as good (in terms of compression ratio). Google mostly uses it for real-time compression, for example of network messages - not for long-term storage.

    Just compress it! Of course if you will you ZIP, players will able to just open this zip file and change whatever they want. But you can use less popular compression algorithms which are not supported by default Windows File Explorer. Snappy for example.

What are some alternatives?

When comparing zlib-ng and Snappy you can also consider the following projects:

zstd - Zstandard - Fast real-time compression algorithm

ZLib - A massively spiffy yet delicately unobtrusive compression library.

LZ4 - Extremely Fast Compression algorithm

Minizip-ng - Fork of the popular zip manipulation library found in the zlib distribution.

brotli - Brotli compression format

libdeflate - Heavily optimized library for DEFLATE/zlib/gzip compression and decompression

LZMA - (Unofficial) Git mirror of LZMA SDK releases

uzlib - Radically unbloated DEFLATE/zlib/gzip compression/decompression library. Can decompress any gzip/zlib data, and offers simplified compressor which produces gzip-compatible output, while requiring much less resources (and providing less compression ratio of course).

tiny_jpeg.h - Single header lib for JPEG encoding. Public domain. C99. stb style.
