20%? That's weak :P I have 3.32x refcompressratio on my /home partition in my dev VM (using gzip-7 here).

  You might look into using xz(lzma) or zstd in place of gzip. Gzip offers pretty poor compression per CPU time performance compared to these newer options. https://clearlinux.org/blogs/linux-os-data-compression-options-comparing-behavior https://clearlinux.org/blogs/linux-os-data-compression-optio...

    ZFS doesn't support either yet: http://open-zfs.org/wiki/Performance_tuning http://open-zfs.org/wiki/Performance_tuning Though it looks like zstd is coming, which is exciting: https://reviews.freebsd.org/D11124 https://reviews.freebsd.org/D11124

    zfs doesn't support either of those yet unfortunately. I'd love for zstd to be available given it's benefits in speed and compression ratio.
