The "Queries Per Second Benchmark" allows you to get a quick overview of the throughput and latency characteristics of grpc.

To build the benchmark type

$ ./gradlew :grpc-benchmarks:installApp

from the grpc-java directory.

You can now find the client and the server executables in benchmarks/build/install/grpc-benchmarks/bin.

The C++ counterpart can be found at https://github.com/grpc/grpc/tree/master/test/cpp/qps
