compression, zstd, filesystems, btrfs, zfs

zstd is a new and already well supported compression format. An HN remark that zstd’s performance curve fits entirely within gzip’s prompted me to convert some of my archived data. Pretty good indeed! Not any larger than the preceding 7z and zip. This analysis confirms that zstd on a high compression level setting is equivalent to xz but much faster to decompress.

ZFS and btrfs also support transparent zstd compression, which I switched on immediately!
