LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (> 0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/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. Benchmarks ---------- The benchmark uses the [Open-Source Benchmark program by m^2 (v0.14.2)](http://encode.ru/threads/1371-File
In this case, compression time is completely ignored. Because only content developers compress the data at once and usually they don't care about its computational cost. But they always care enduser's experience a.k.a. "loading time" and bandwidth.
Please pay attention to "LZ4HC -9" which is quite faster than other methods.
