Upgrade the 12 years old LZMA libraries of coreboot and SeaBIOS for +120% / +180% decompression speed increase
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
