Netty-Socketio Windows 性能测试
Netty-Socketio Windows性能测试
测试机器配置
服务器：
- 操作系统：Windows Server 2008 R2 Enterprise
- CPU：Intel i3-3220
- 内存：8GB
- JDK： 1.7.0_71-b14 64bit
测试机：
- 操作系统：Windows Server 2008 R2 Enterprise
- CPU：Intel G2030
- 内存：6GB
Windows Server 2008 R2网络调优
编写net.reg文件（双击导入注册表，并重新启动机器 ），内容如下：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters]
"ForwardBroadcasts"=dword:00000000
"IPEnableRouter"=dword:00000000
"UseDomainNameDevolution"=dword:00000001
"EnableICMPRedirect"=dword:00000000
"DeadGWDetectDefault"=dword:00000000
"DontAddDefaultGatewayDefault"=dword:00000000
"TcpTimedWaitDelay"=dword:0000001e
"SynAttackProtect"=dword:00000002
"TcpMaxPortsExhausted"=dword:00000005
"TcpMaxHalfOpen"=dword:000001f4
"TcpMaxHalfOpenRetried"=dword:00000190
"MaxUserPort"=dword:0000fffe
"TcpMaxConnectResponseRetransmissions"=dword:00000002
"TcpMaxDataRetransmissions"=dword:00000002
"KeepAliveTime"=dword:000493e0
以上配置调整了最大可用端口，并启动了半连接数安全设置，使服务器具有一定的防攻击能力，因此在客户端测试连接时，如果同时并发数过多，可能会导致部分连接失败。
测试程序
服务端程序
使用官方示例 ：
https://github.com/mrniko/netty-socketio-demo
并做以下修改：
EventChatLauncher
public class EventChatLauncher {
private static final Logger log = LoggerFactory.getLogger(EventChatLauncher.class);
public static void main(String[] args) throws InterruptedException {
Configuration config = new Configuration();
//config.setHostname("localhost");
config.setPort(9092);
final SocketIOServer server = new SocketIOServer(config);
server.addEventListener("chatevent", ChatObject.class, new DataListener() {
@Override
public void onData(SocketIOClient client, ChatObject data, AckRequest ackRequest) {
//server.getBroadcastOperations().sendEvent("chatevent", data);
client.sendEvent("chatevent", data);
log.warn(server.getAllClients().size()+":"+data.getUserName()+":"+data.getMessage());
}
});
server.start();
Thread.sleep(Integer.MAX_VALUE);
server.stop();
}

客户端测试程序
使用node做测试，本次测试使用的node版为5.12.0 64位
node安装请参数其他文档
测试脚本test.js
var count = 0;
var max = 2000;
var sockets = new Array();
for(var i=0;ifunction socketClient(id) {
var userName = 'user' + id;
var message = 'message' + id;
var io = require('socket.io-client');
var socket = io.connect('http://192.168.1.199:9092',{'force new connection': true});
socket.on('connect', function() {
sockets[id]=socket;
count++;
console.log('id:'+id+':connect count:'+count);
//socket.emit('chatevent', {userName: userName, message: message});
});
} 在测试脚本目录下执行以下命令：
npm install socket.io-client
测试运行
服务端
通过mvn clean package打包，在target下生成：netty-socketio-1.0.jar
编写启动批处理：
start-server.bat
java -server -Xms1024m -Xmx2048m -XX:PermSize=128m -XX:MaxPermSize=256m -jar netty-socketio-1.0.jar运行批处理程序：start-server.bat
客户端
编写启动批处理：
start-client.bat
node test.js运行批处理程序：start-client.bat
每次建立2000个连接，在连接建立后发送一条消息，服务器回复同样消息。
可重复运行以上批处理文件。
初步测试结果
在连接数达到2万左右时，服务器CPU占用已经非常高，经常在90%以上
在连接数达到6万左右时，服务器CPU长期维持在90%以上，但仍能继续连接客户端，在6.3左右连接时，已经出现连接缓慢及失败现象。需要使用多网卡及更好的CPU
