# 설치 가이드

1. 코드 내려받기

git clone https://github.com/plutov/benchmark-grpc-protobuf-vs-http-json

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd benchmark-grpc-protobuf-vs-http-json

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Go

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Go Go 언어 컴파일러 및 도구 모음입니다.

go build ./...

Go 프로그램을 컴파일해 실행 파일을 만듭니다.

go run .

따로 빌드하지 않고 바로 Go 프로그램을 실행합니다.

✅ 빌드가 에러 없이 끝나면 성공입니다. go run . 을 썼다면 터미널 출력을 확인하세요.

### gRPC+Protobuf or JSON+HTTP?

This repository contains 2 equal APIs: gRPC using Protobuf and JSON over HTTP. The goal is to run benchmarks for 2 approaches and compare them. APIs have 1 endpoint to create user, containing validation of request. Request, validation and response are the same in 2 packages, so we're benchmarking only mechanism itself. Benchmarks also include response parsing.

### Requirements

- Go 1.11

### Run tests

Run benchmarks:
```
GO111MODULE=on go test -bench=. -benchmem
```

### Results

```
goos: darwin
goarch: amd64
BenchmarkGRPCProtobuf-8            10000            117649 ns/op            7686 B/op        154 allocs/op
BenchmarkHTTPJSON-8                10000            105837 ns/op            8932 B/op        116 allocs/op
PASS
ok      github.com/plutov/benchmark-grpc-protobuf-vs-http-json  4.340s
```

They are almost the same, HTTP+JSON is a bit faster and has less allocs/op.

### CPU usage comparison

This will create an executable `benchmark-grpc-protobuf-vs-http-json.test` and the profile information will be stored in `grpcprotobuf.cpu` and `httpjson.cpu`:

```
GO111MODULE=on go test -bench=BenchmarkGRPCProtobuf -cpuprofile=grpcprotobuf.cpu
GO111MODULE=on go test -bench=BenchmarkHTTPJSON -cpuprofile=httpjson.cpu
```

Check CPU usage per approach using:

```
go tool pprof grpcprotobuf.cpu
go tool pprof httpjson.cpu
```

My results show that Protobuf consumes less ressources, around **30% less**.

### gRPC definition

- Install [Go](https://golang.org/dl/)
 - Install [Protocol Buffers](https://github.com/google/protobuf/releases)
 - Install protoc plugin: `go get github.com/golang/protobuf/proto github.com/golang/protobuf/protoc-gen-go`

```
protoc --go_out=plugins=grpc:. grpc-protobuf/proto/api.proto
```
