invesitgate the use of byte-strings

[PythonFZ]

Instead of encoded data send it as byte strings for performance?

[PythonFZ]

From a size perspective, as expected, there is no real difference:

data = json.dumps({"a": np.random.normal(size=((500, 500))).tolist()})
print((sys.getsizeof(data) * ureg.byte).to(ureg.megabyte))
# 5.158796 megabyte
print((sys.getsizeof(data.encode()) * ureg.byte).to(ureg.megabyte))
# 5.158788 megabyte
