近期在开发一个抢口罩的系统，类似于电商常见的秒杀系统。其时选型的的时候筹备在netcore和golang之间选择一个作为系统的开发语言，网上的说法各异，有的说iris快，有的说.netcore快。于是决定本身做下测试。

iris在go的web开发框架中长短常风行的，它本身的介绍是最快的go语言web框架，这个必定有一家之言的身分，但是说它是最快的go框架之一必定没有问题。使用的iris的版本是12.1.8

aspnetcore 就是微软在.netcore中开发的标准框架，不需要用到其他第三方框架。这里使用的.netcore版本是3.0

iris的代码为：

// package main // import "github.com/gin-gonic/gin" // func main() { // r := gin.Default() // r.GET("/ping", func(c *gin.Context) { // c.JSON(200, gin.H{ // "message": "pong", // }) // }) // r.Run() // listen and serve on 0.0.0.0:8080 (for windows "localhost:8080") // } package main import ( "github.com/kataras/iris" "github.com/kataras/iris/context" //"strings" "math/rand" ) const letterBytes = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 " func randomString(n int) string { b := make([]byte, n) for i := range b { b[i] = letterBytes[rand.Intn(len(letterBytes))] } return string(b) } func main() { app := iris.New() //txt := strings.Repeat("g", 10000) app.Get("/api/values/{id}", func(ctx context.Context) { txt := randomString(1024) ctx.WriteString(txt) }) app.Run(iris.Addr(":5000")) }

aspnetcore的代码为:(吐槽一下，微软整的代码太多，让人有点添堵)

public class Program { public static void Main(string[] args) { CreateHostBuilder(args).Build().Run(); } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseKestrel(options => { options.Listen(IPAddress.Any, 5080); //HTTP port }); webBuilder.UseStartup<Startup>(); }).ConfigureLogging(a => a.SetMinimumLevel(LogLevel.None)); }

public class Startup { // This method gets called by the runtime. Use this method to add services to the container. // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940 public void ConfigureServices(IServiceCollection services) { } const string chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 "; static string RandomString(int length) { var random = new Random(DateTime.Now.Millisecond); var bytes = new Char[length]; for (var i = 0; i < length; i++) { bytes[i] = chars[random.Next(chars.Length)]; } return new string(bytes); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseRouting(); app.UseEndpoints(endpoints => { endpoints.MapGet("/", async context => { var txt = RandomString(1024); await context.Response.WriteAsync(txt); // await context.Response.WriteAsync("Hello World!"); }); }); } }

windows下的测试：

iris: 通过 go build 进行编译，然后运行。启用 bombardier测试。功效如下

bombardier.exe -c 50 -n 300000 :5000/api/values/id

Bombarding :5000/api/values/id with 300000 request(s) using 50 connection(s)

aspnetcore: dotnet publish -c Release 编译。功效如下

Bombarding :5080 with 300000 request(s) using 50 connection(s)
300000 / 300000 [=================================================================================] 100.00% 34749/s 8s

功效让人大跌眼镜。.netcore比iris 的qps快了4倍以上。（注意上面代码，我移除了.netcore的日志）

因为是windows平台的功效，我怀疑go语言在windows没有优化，所以后来插手了linux amd64的测试
