Lempel–Ziv Ross Williams (LZRW) refers to variants of theLZ77lossless data compressionalgorithms with an emphasis on improving compression speed through the use ofhash tables and other techniques. This family was explored byRoss Williams, who published a series of algorithms[1] beginning with LZRW1 in 1991.
The variants are:
TheLZJB algorithm used inZFS is derived from LZRW1.
