Antoine Pitrou commented on ARROW-1715:
---------------------------------------
I think it will be down to differences in metadata serialization overhead,
because in both cases you end up copying the buffer contents into the pickle
stream (and actually there's a second copy before that, as pickle will only
allow serializing a bytes object, not a zero-copy buffer).
