> {quote}
> Snappy is a compression/decompression library. It does not aim for maximum
> compression, or compatibility with any other compression library; instead, it
> aims for very high speeds and reasonable compression. For instance, compared
> to the fastest mode of zlib, Snappy is an order of magnitude faster for most
> inputs, but the resulting compressed files are anywhere from 20% to 100%
> bigger. On a single core of a Core i7 processor in 64-bit mode, Snappy
> compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec
> or more.
