The name is an acronym for Lempel–Ziv + Finite State Entropy (implementation of asymmetric numeral systems). LZFSE was introduced by Apple at its Worldwide Developer Conference (WWDC) 2015. It shipped with that year's iOS 9 and OS X 10.11 releases.
Apple claims that LZFSE compresses with a ratio comparable to that of zlib (DEFLATE) and decompresses 2–3x faster while using fewer resources, therefore offering higher energy efficiency. It was aimed for scenarios where decompression speed and rate should be prioritised equally. Part of this energy efficiency was achieved by optimising the algorithm for modern micro-architectures, specifically focusing on arm64.
