Prefork Example

Github StackBlitz

This project demonstrates how to use the Prefork feature in a Go application using the Fiber framework. Preforking can improve performance by utilizing multiple CPU cores.

Prerequisites​

Ensure you have the following installed:

Setup​

  1. Clone the repository:

    git clone https://github.com/gofiber/recipes.git
    cd recipes/prefork

  2. Install dependencies:

    go get

Running the Application​

  1. Start the application: 
    go run main.go

Example​

Here is an example of how to set up the Prefork feature in a Fiber application:

package main

import (
    "fmt"
    "log"
    "os"

    "github.com/gofiber/fiber/v3"
)

func main() {
    // Print current process
    if fiber.IsChild() {
        fmt.Printf("[%d] Child\n", os.Getppid())
    } else {
        fmt.Printf("[%d] Master\n", os.Getppid())
    }

    // Fiber instance
    app := fiber.New()

    // Routes
    app.Get("/", hello)

    // Start server with prefork enabled
    log.Fatal(app.Listen(":3000", fiber.ListenConfig{EnablePrefork: true}))
}

// Handler
func hello(c fiber.Ctx) error {
    return c.SendString("Hello, World!")
}
