Description

Igor Pavlov (7z/LZMA SDK author) told me a few months ago that

Decompression speed for lzma:
lzma sdk 18.03 C code - about +120% speed increase from 4.42.
lzma sdk 18.03 asm-x64 code - about +180% speed increase from 4.42.

Such a huge speed increase is a good reason to upgrade these ancient LZMA libraries
