How do I enable python grpc+protobuf cpp_implementation?

[Yan Yan]

This cpp_implementation thing is supposed to make protobuf faster.

python setup.py build --cpp_implementation

https://github.com/google/protobuf/tree/master/python

Am I running the cpp_implementation of protobuf if I installed grpc thru pip grpcio?

easy_install --user pip
pip install pip --upgrade --user
pip install grpcio-tools --user
pip install grpcio --user --upgrade

The youtube here mentioned that python gRPC is a wrapper on the C version of gRPC.

When I am running python gRPC, which part of the solution stack consumes more time? the RPC part or the protobuf serialization part? Thx.
