準備工作
Go（基於Gin）與 Net Core 準備一最簡單的接口，爲避免影響，不返回任何數據。
Go ：test.go
package test
import (
"github.com/gin-gonic/gin"
)
func Index(c *gin.Context) {
c.Done()
}
Go：router.go
func InitRouter() *gin.Engine {
router := gin.New()
router.GET("/favicon.ico", func(c *gin.Context) {
})
testRouter := router.Group("test")
{
testRouter.GET("index", test.Index)
}
return router
}
Go：main.go
package main
import (
"findo.api/conf"
"findo.api/router"
"findo.api/services/redis"
)
func main() {
router := router.InitRouter()
router.Run()
}
測試Go應用
Net Core
MainController.cs，/main/index不做任何處理
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Options;
namespace Findo.Controllers {
[Route ("Main")]
public class MainController {
private IHttpContextAccessor _accessor;
public MainController (IHttpContextAccessor accessor) {
_accessor = accessor;
}
[AllowAnonymous]
[HttpPost]
[HttpGet]
[Route ("index")]
public void index () {
}
}
}

測試比較：
1､鏡像大小比較
fengyideMacBook-Pro:Downloads fengyi$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
fengyily/netcore.findo.api v2 70d6599dcdb0 2 hours ago 264MB
fengyily/go.findo.api auto d9cb3d8ac5ac 2 hours ago 21.8MB
由於go應用是基於 alpine製作，大小隻有 21M，.net core應用 264M
2､壓力測試：使用wrk壓測。
先安裝wrk
git clone https://github.com/wg/wrk.git
cd wrk
make

3.1的鏡像比 2.1的鏡像要少不少，打出來的鏡像也小 50M左右，接下來測試對比下

Go性能確實優秀，幾乎是.Net Core 的4倍，net core 3.1性能比2.1也有30%左右的提升，但還是遠不如GO的性能。
待有時間，再把Java、PHP、Python加入到測試中比較。
