How freearc could be even better

[calthax]

Implement XXHash Because it passes smhasher on all 10 tests while crc32 passes only 9

[Bulat Ziganshin]

umac is up to 4x faster than xxhash, easily scaled to any length of 32*N bits, and have much stronger gurantees of its quality

Can you add FSE to your tornado compressor Here is the license of FSE https://github.com/Cyan4973/FiniteSt...master/LICENSE
What version of the gpl does tornado use

[Bulat Ziganshin]

in tornado, difference between lzari and lzhuf compression ratios are about 0.5%, so that's not on priority list

[Jarek]

Compression rate is not the only advantage of FSE/ANS - as you don't need to build the trees, it is also much faster - look at zhuff and lzturbo at this benchmark:
