xz
lzham: The build system is not well-polished for Linux. I have forked it, fixed build errors due to stdint.h, and installed lzhamtest. IMHO the command line program lzhamtest should be renamed to lzham.
kanzi: There are a wide variety of transforms and entropy encoders, unusual for a compresion program. For the compression speed of enwik8, it's Pareto superior to xz, but decompression is slower.
