Server Benchmark Comparison: Go, PHP, and Node.js

This repository contains simple HTTP servers written in Go, PHP, and Node.js. The goal is to compare the performance of these servers by benchmarking them using wrk.

Use the instructions below to run and benchmark each server.

Setup

Prerequisites

• Install Go (ideally Go 1.20 or later)
• Install PHP (ideally PHP 8.2 or later)
• Install Node.js (ideally Node.js 20 or later)
• Install OpenSwoole (Needed to run the Swoole server)
• Install wrk for benchmarking

Installing wrk

On Linux, you can install wrk with the following commands:

sudo apt-get update
sudo apt-get install build-essential libssl-dev git -y
git clone https://github.com/wg/wrk.git
cd wrk
make
sudo cp wrk /usr/local/bin

Running the Servers

Go Server

Navigate to the go directory and run the following command:

go run main.go

The server will start on http://localhost:8080.

PHP Server

Navigate to the php directory and run the following command:

php -S localhost:8080

The server will start on http://localhost:8080.

Node.js Server

Navigate to the node directory and run the following command:

node server.js

The server will start on http://localhost:8080.

OpenSwoole Server

Navigate to the swoole directory and run the following command:

php -d extension=swoole.so index.php

The server will start on http://localhost:8080.

Benchmarking the Servers

Use wrk to benchmark the servers. Open a new terminal window and run the following command:

wrk -t12 -c400 -d30s http://localhost:8080

This command will run wrk with:

• -t12: 12 threads
• -c400: 400 connections
• -d30s: for a duration of 30 seconds

Adjust the parameters as needed to better understand the server’s capabilities under different loads.

Example Output

The output will show statistics like requests per second, latency, and more. Example:

Running 30s test @ http://localhost:8080
  12 threads and 400 connections
  Thread Stats   Avg      Stdev     Max   +/- Stdev
    Latency    10.09ms    4.95ms  45.79ms   65.22%
    Req/Sec     3.33k     1.33k    8.18k    69.19%
  1194183 requests in 30.10s, 152.23MB read
Requests/sec:  39694.77
Transfer/sec:      5.06MB

Notes

• Ensure that only one server is running at a time on port 8080 to avoid conflicts.
• Adjust the parameters of the wrk command as needed to better understand the server’s capabilities under different loads.
