Instructions

For generating load, ghz is used. For the purposes of this README, it is assumed that ghz is installed in the $PATH.

Start a server on port 3000:

$ node server-grpc-js.js
... or
$ node server-grpc.js
... or
$ ./bin/go-grpc-{arch}

Gather all the datas:

$ ghz -proto ./echo.proto -insecure -z 40s -c 100 -call EchoService/Echo -d '{}' localhost:3000

To test that the service is working run the following:

$ grpcurl --plaintext --proto echo.proto localhost:3000 EchoService/Echo

Results

These are the results on macOS Mojave running on a late 2016 MBP with:

• 2.7 GHz Intel Core i7
• 16 GB 2133 MHz LPDDR3

CPU Usage

Using the sampleproc dtrace script the % of utilization of each process across all CPUs was determined, below are the results. Additionally, running the topsysproc script provided information about the number of syscalls for each during a 1 second period, which is also shown below.

Process	% CPU Usage	# of Samples	Avg Syscall Count
node	14	4596	2500
rust	14	4511	80000
go	30	10079	120000

Below are htop results for each of the processe. As you can see, memory usage remained low for each process as well, with Node.js using the most.
