# FastAPI vs Gin vs Fiber

An experiment to compare performance of FastAPI, Gin and Fiber.

## Overview:

- [Setup](#setup)
- [Run experiments](#run-experiments)
- [Results](#results)

## Setup

### FastAPI

The repository uses Python 3.11. Follow the steps below to get started:

- Create conda environment:

```bash
conda create -n fastapi-tests python=3.11 -y
conda activate fastapi-tests
```

You can choose any other environment manager of your choice.

- Install dependencies:

```bash
pip install -r requirements.txt
```

**Note**: All requirement files are generated using `pip-tools`.

### Gin

The repository uses Go 1.21. Follow the steps below to get started:

- Install dependencies:

```bash
go mod tidy
```

## Run experiments

Both FastAPI and Gin applications serve one endpoint:

- `/`: sleeps for 10 seconds and returns a response

### FastAPI

The experiment uses `gunicorn` server to run the FastAPI application.

```bash
gunicorn -k uvicorn.workers.UvicornWorker app:app
```

### Gin

The experiment uses `gin` server to run the Gin application.

```bash
go run gin/app.go
```

### Fiber

The experiment uses `fiber` server to run the Fiber application.

```bash
go run fiber/app.go
```

### wrk Benchmarking

Run the benchmarking script:

```bash
./benchmark.sh
```

**Note**: The script uses `wrk` to run benchmarks on http://localhost:8000.
You should benchmark one application at a time.
