Description

As newer compression algorithms are developed and integrated into ZFS, the default compression algorithm, which is used when a dataset is configured with "compression = on", should also be re-evaluated. Based on the extensive benchmarking of lz4, and the pre-existing change to use lz4 for metadata, it is clear that lz4 is a better choice than lzjb for ZFS's default compression algorithm.
