tensorflow-serving-benchmark

I couldn't find any benchmarks of TensorFlow Serving and wanted to know the throughput of the native gRPC client compared to a REST-based client that forwards requests to the a gRPC client (which most people are likely to use for external-facing services).

Usage and Results

gRPC (async)

docker-compose run grpc-benchmark

Creating tensorflowservingbenchmark_server_1 ... done

10000 requests (10 max concurrent)
2487.13826442827 requests/second

WSGI (gunicorn/falcon, four workers, sync)

docker-compose run wsgi-benchmark

Starting tensorflowservingbenchmark_server_1 ... done
Creating tensorflowservingbenchmark_wsgi-client_1 ... done
