Ok, comparison between zlib/snappy/lz4:
$ python3.4 -m timeit -s "import zlib; data =
zlib.compress(open('Lib/__pycache__/threading.cpython-35.pyc', 'rb').read());
print(len(data))" "zlib.decompress(data)"
10000 loops, best of 3: 181 usec per loop
$ python3.4 -m timeit -s "import snappy; data =
snappy.compress(open('Lib/__pycache__/threading.cpython-35.pyc', 'rb').read());
print(len(data))" "snappy.decompress(data)"
10000 loops, best of 3: 35 usec per loop
$ python3.4 -m timeit -s "import lz4; data =
lz4.compress(open('Lib/__pycache__/threading.cpython-35.pyc', 'rb').read());
print(len(data))" "lz4.decompress(data)"
10000 loops, best of 3: 21.3 usec per loop
