   * Snappy's main target is very high-speed compression/decompression with reasonable compression size. Although the compression ratio of snappy-java is modest and about the same as `LZF` (ranging 20%-100% according to the dataset), among the Java-based compressors in the benchmark snappy-java is as fast as the fastest for compression, and the decompression speed is 2x as fast to the others.
