.NET Core First Look

.NET Core

 

First Look at the scenario for the game server development. So testing on focus and stronger in IO-intensive computing

 

Network IO:

NetCore：60%CPU QPS 56W

C++：31%CPU QPS 58W

C++：68%CPU QPS 124W

 

C # test code

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Threading; using System.Collections; using System.Collections.Generic; namespace ConsoleApp2 { class Session { public TcpClient client = null; public void Go() { client.GetStream().BeginRead(bytes, pos, 32 - pos, AsyncReadCallback, this); } void AsyncReadCallback(IAsyncResult ar) { if (ar.IsCompleted) { var sess = ar.AsyncState as Session; sess.client.GetStream().BeginWrite(sess.bytes, sess.pos, 32, AsyncWriteCallback, sess); } } void AsyncWriteCallback(IAsyncResult ar) { if (ar.IsCompleted) { var sess = ar.AsyncState as Session; sess.client.GetStream().BeginRead(sess.bytes, sess.pos, 32, AsyncReadCallback, sess); } } int pos = 0; byte[] bytes = new byte[32]; } class Program { static void worker(object obj) { while(true) { Thread.Sleep(1); lock(obj) { var que = obj as Queue<Session>; if(que.Count>0) { que.Dequeue().Go(); } } } } static void Main(string[] args) { var ss = new TcpListener(12125); ss.Start(); var bytes = new byte[32]; var ths = new Thread[50]; var que = new Queue<Session>[50]; int i = 0; foreach(var p in ths) { que[i] = new Queue<Session>(); ths[i] = new Thread( (worker)); ths[i].Start(que[i]); ++i; } int balance = 0; while (true) { balance = ++balance % que.Length; var sess = new Session(); var task = ss.AcceptTcpClientAsync(); while (task.IsCompleted == false) { var cli = task.Result; sess.client = cli; lock (que[balance]) { que[balance].Enqueue(sess); } } } ss.Stop(); Console.WriteLine("Hello World!"); } } }
