- I tested [FLIF](https://flif.info/) compression on ~200 MB file. Compression ratio was good but the speed on the other hand was really bad. Decompression wasn't better, it was slow too.

- Even lossy compression was slow. This compression is probably only good for small images.

- Next step is to test B3D compression.

- Pure LZW creates dictionary as it goes. Can create entries which aren't found in data.
- LZ77 is better variant.
-**Look at Huffman encoding, then maybe Arithmetic and in a spare time install nVidia drivers to test ot B3D library.**
