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
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!
