LZ4 compression library, lossless and very fast
LZ4 is a very fast lossless compression algorithm, providing compression speed at 400 MB/s per core, scalable with multi-cores CPU. It also features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
A high compression derivative, called LZ4_HC, is also provided. It trades CPU time for compression ratio.
The libraries are BSD licensed, and the binaries are GPLv2.
