Just an idea - did you try to run `ghz` with the `--async` flag. It might make 
sense to play around with `--skipFirst` flag as well, so that first request to 
not pre-warmed JVM do not bias the result.
Also - looks like REST wrk benchmark uses 400 connections, while gRPC ghz just 
one? Consider trying `--connections=400` ghz argument.
Docs: https://ghz.sh/docs/usage


Already did all of that and more:

* played with `--async`, `--concurrency` and `--connections`

* invoked ghz multiple times to make sure server is "warm"

Like I already mentioned, I even wrote my own benchmark that gave *somewhat* 
better throughput than ghz, but still way lower than REST tests.

If no one can spot anything I missed on server side, I'll also write my own 
benchmarks for REST endpoints - that way I can guarantee that client logic is 
the same.

Re: [grpc-io] Re: gRPC performance benchmark

2018-11-07 Thread robert engels 
I would think it is going to depend heavily on the work the gRPC service method 
does, not GRPC itself. Since the REST/HTTP protocol is already less efficient 
than the gRPC one - the former is going to dominate it in terms of relative 
performance.

Thanks for bringing this to our attention. The numbers look very low for
C++ (especially for unary, its way too low). We are investigating..

thanks,
