2023年1月12日 — My most important tuning is to turn on compression on the right datasets, and create datasets fine-graded enough to separate out non-compressible things.

2023年10月6日 — Apparently, an upcoming feature for ZFS is a complete re-imagining of how inline compression will be used.

2021年11月18日 — ZFS compression works at the file system (zfs) or logical volume (zvol) level on a record-by-record basis, rather than on an entire zpool.

2021年4月20日 — The current default compression algorithm is either lzjb or, if the lz4_compress feature is enabled, lz4. So the default should be lz4.

2015年8月7日 — To use a different algorithm, use for example compression=lz4 instead of on. lz4 is likely the best choice now. It has been tested ...

Originally ZFS supported a small number of compression algorithms: LZJB (an improved Lem- pel–Ziv variant created by Jeff Bonwick, one of the co-creators of ZFS ...

Compression is the process where data is stored using less disk space. The following compression algorithms are available.

2022年2月18日 — In a first set of measurements I compare the performance and efficiency for the most common used compression algorithms: off, on, gzip, lz4, zstd.
