Benchmarks

snappy vs. zlib

Compressing:

%timeit zlib.compress("hola mundo cruel!")
100000 loops, best of 3: 9.64 us per loop

%timeit snappy.compress("hola mundo cruel!")
1000000 loops, best of 3: 849 ns per loop

Snappy is 11 times faster than zlib when compressing

Uncompressing:

r = snappy.compress("hola mundo cruel!")

%timeit snappy.uncompress(r)
1000000 loops, best of 3: 755 ns per loop

r = zlib.compress("hola mundo cruel!")

%timeit zlib.decompress(r)
1000000 loops, best of 3: 1.11 us per loop

Snappy is twice as fast as zlib
