is an extremely fast non-cryptographic hash algorithm, working at speeds close to RAM limits. It is proposed in two flavors, 32 and 64 bits.
is lossless compression algorithm, providing compression speed at 400 MB/s per core (0.16 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open source software using a BSD license.
