ZFS should support ZStandard compression
ZStandard ([[http://www.zstd.net/]]) is a new compression algorithm from the creator of LZ4 (the default compression algorithm in ZFS). It provides a wider range of compression levels ranging from faster than LZ4, to better compression than GZIP. On many cases it is 4-5x faster than GZIP while providing comparable or better compression ratios.
