- A very simple algorithm that only compresses zeroes. - A very simple algorithm that only compresses zeroes.
- ZSTD (Zstandard)
- Zstandard is a modern, high performance, general compression
algorithm which provides similar or better compression levels to
GZIP, but with much better performance. Zstandard offers a very
wide range of performance/compression trade-off, and is backed by
an extremely fast decoder.
It is available from `OpenZFS 2.0 version <https://github.com/openzfs/zfs/pull/10278>`__.
If you want to use compression and are uncertain which to use, use LZ4. If you want to use compression and are uncertain which to use, use LZ4.
