Here are two alternative Python protobuf implementations. They're each about 15x faster than the pure Python implementation from Google. fast-python-pb - codegen wrapping Google's C++ protobuf implementation. https://github.com/Greplin/fast-python-pb https://github.com/Greplin/fast-python-pb lwpb - non-codegen using a protobuf implementation in C.
