    According to these https://github.com/lz4/lz4 values you need around ten (10) quite modern cores in parallel to accomplish around 8GB/s.

    > The downside of lz4 is that it can’t be configured to run at higher & slower compression ratios.

    lz4 has some level of configurability? https://github.com/lz4/lz4/blob/v1.9.4/lib/lz4frame.h#L194

    There's also LZ4_HC.

    Get your bootloader unlocked via Download mode and then obtain your stock firmware, preferably for your current region https://samfw.com (Download mode: CARRIER_CODE). Get the boot image from AP with 7zip, unpack from LZ4 with https://github.com/lz4/lz4/releases (drag and drop), patch with Magisk https://github.com/topjohnwu/magisk/releases/latest, grab the new image, name it "boot.img" and pack it into a .tar with 7zip and flash to AP with odin https://odindownload.com

    After some investigations and experiments, I found out that it was the PNG compression (well, decompression I should say) that took a while. So I've made some experiments using the LZ4 compression library, which is focused on decompression speed, and it turned out to be an excellent solution!

    If anyone just cares for speed instead of compression I’d recommend lz4 [1]. I only recently started using it. Its speed is almost comparable to memcpy.

    Getting lost in material models is tempting. But, at this point you are overdue for working on your own asset pipeline. glTF is great. But, you should learn how to do it yourself. The hardest part will be reading source asset files. The FBX SDK is painful. Assimp isn't great either. Writing your own exporter to your own intermediate text format from Maya or Blender would be good if you are up for it. From whatever source, make your own archive format and binary formats for meshes, animations, textures and scenes. Use https://github.com/lz4/lz4 for compression. You should be able to decompress a list of assets into a big linear array and use them right there with just a bit of pointer fix-up. Minimize the amount of memory you have to touch from start to finish. Data that is going to the GPU (textures, vertex/index buffers) should decompress straight into mapped buffers for fast uploads.
  • LZ4, an Extremely Fast Compression Algorithm

    I'm not a fan of the stacked bar charts, I like the table of data for "Benchmarks" on the github source page: https://github.com/lz4/lz4

    It makes it very clear where LZ4 fits into comparisons with compression speed, decompression speed and compression ratio

We haven't tracked posts mentioning LZFSE yet.
Tracking mentions began in Dec 2020.

What are some alternatives?

When comparing LZ4 and LZFSE you can also consider the following projects:

zstd - Zstandard - Fast real-time compression algorithm

Snappy - A fast compressor/decompressor

brotli - Brotli compression format

LZMA - (Unofficial) Git mirror of LZMA SDK releases

ZLib - A massively spiffy yet delicately unobtrusive compression library.

7-Zip-zstd - 7-Zip with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard

LZHAM - Lossless data compression codec with LZMA-like ratios but 1.5x-8x faster decompression speed, C/C++

RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.

zlib-ng - zlib replacement with optimizations for "next generation" systems.

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