LZMA – Improved and optimized version of LZ77 algorithm
PPMD – Dmitry Shkarin’s PPMdH with small changes
BCJ – Converter for 32-bit x86 executables
BCJ2 – Converter for 32-bit x86 executables
BZip2 – Standard BWT algorithm
Deflate – Standard LZ77-based algorithm

LZMA is the default and general compression method of 7z format. The main features of LZMA are:
High compression ratio
Variable dictionary size (up to 4 GB)
Compression speed: about 1 MB/s on 2 GHz CPU
Decompression speed: about 10-20 MB/s on 2 GHz CPU
Small memory requirement for decompression (depend from dictionary size)
Small code size for decompression: about 5 KB
Supports multi-threading and P4’s hyper-threading
