LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s
|
|
per core, scalable with multi-cores CPU. It features an extremely fast decoder,
|
|
with speed in multiple GB/s per core, typically reaching RAM speed limits on
|
|
multi-core systems.
|
|
|
|
Speed can be tuned dynamically, selecting an "acceleration" factor which trades
|
|
compression ratio for faster speed. On the other end, a high compression
|
|
derivative, LZ4_HC, is also provided, trading CPU time for improved compression
|
|
ratio. All versions feature the same decompression speed.
|
|
|
|
LZ4 is also compatible with dictionary compression, both at API and CLI levels.
|
|
It can ingest any input file as dictionary, though only the final 64KB are used.
|
|
This capability can be combined with the Zstandard Dictionary Builder, in order
|
|
to drastically improve compression performance on small files.
