设置Go + Gin服务器并在负载下获得13秒的响应时间

Update: Answered question with results from the web server hosted on VPS (Vultr)

I compared it against a NodeJS/Express server to achieve a point of comparison.

What have I done wrong?

Go server:

package main

import "github.com/gin-gonic/gin"

func main() {
    gin.SetMode(gin.ReleaseMode)
    router := gin.Default()
    router.GET("/ping", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "pong",
        })
    })
    router.Run("0.0.0.0:9999")
}

Express Server:

const express = require('express')
const app = express()

app.get('/ping', (req, res) => res.send({ pong: 'pong' }))

app.listen(9999, () => console.log('Example app listening on port 9999!'))

Test

Tool was Vegeta

echo "GET http://localhost:9999/ping" | vegeta attack -rate=500 -duration=10s | vegeta report    

Duration: 10s
Requests: 500 per s

Results

Go/Gin's Mean Response Time: 13000ms

Node/Express's Mean Response Time: 24ms

I put the test up on a VPS and compared their results. Looks like Go is king
