Benchmark compare with grpcio

[ipfans]

I think it is great to create benchmark comparation with grpcio.

E.x. throughputs/latency/...

It is hard to create fair and representative benchmarks. That's why I don't have them yet. But I definitely will have them in the future. And not to compete with grpcio, but to improve grpclib and prevent regressions.

Let's keep it open until finish first brenchmark 😄

Seems like benchmarks for gRPC already exists and we can adapt them: https://grpc.io/docs/guides/benchmarking.html

Great source of cases for writing helpful benchmarks: https://blogs.dropbox.com/tech/2019/01/courier-dropbox-migration-to-grpc/
