Lrzip
Long Range Zip (Lrzip) is a compression program that can
achieve very high
compression ratios and speed when used with large files. It uses the
combined compression algorithms of zpaq and lzma for maximum
compression, lzo for maximum speed, and the long range redundancy
reduction of rzip.
It is designed to scale with increases with RAM size,
improving compression further. A choice of either size or speed
optimizations allows for either better compression than even lzma can
provide, or better speed than gzip, but with bzip2 sized compression
levels.
Features include:
- Heavily multithreaded with the backend compression and
decompression phase
- Uses an extended version of rzip which does a first pass
long distance redundancy reduction
- Compression algorithm can be chosen to be optimised for
size (lzma - default), speed (lzo), legacy (bzip2) or (gzip) or can be
omitted
- lrzcat - automatically decompresses .lrz files to stdout
- Works with stdin/stdout
- Sliding mmap implementation
