If you have data to the contrary I'd be happy to be wrong, but AFAIK, lz4 will retain its usefulness for some time, at least for ZFS. there are attempts to integrate zstandard in > ZFS, Allan Jude is working on that, That's great, I look forward to it! --matt [*] According to the zstandard github page, lz4 is 1.5x faster at compression and 3x faster at decompression. https://github.com/facebook/zstd
