Netty WriteAndFlush方法不起作用

看哪以下代码： public final class SecureChatClient { static final String HOST = System.getProperty(“host”, “127.0.0.1”); static final int PORT = Integer.parseInt(System.getProperty(“port”, “8992”)); public static void main(String[] args) throws Exception { // Configure SSL. final SslContext sslCtx = SslContext.newClientContext(InsecureTrustManagerFactory.INSTANCE); EventLoopGroup group = new NioEventLoopGroup(); try { Bootstrap b = new Bootstrap(); b.group(group) .channel(NioSocketChannel.class) .handler(new NetworkInitializer(sslCtx)); // Start the […]

为什么Netty表现不佳？

我用这个例子进行性能测试 有人说netty的表现如此之快。 它可以处理1,00,000+并发请求/秒（请查看以下链接） http://www.jboss.org/netty/performance/20090303-mheath.html http://www.jboss.org/netty/performance/20090607-asalihefendic.html 但是当我尝试使用这个例子时，它只给我107个req / sec，并且有1000个并发请求 ab -n 10000 -c 1000 http://localhost:8080/ Server Software: Server Hostname: localhost Server Port: 8080 Document Path: / Document Length: 230 bytes Concurrency Level: 1000 Time taken for tests: 92.784 seconds Complete requests: 10000 Failed requests: 0 Write errors: 0 Total transferred: 2900000 bytes HTML transferred: 2300000 bytes […]

Netty channel.write不写消息

我正在尝试使用Netty的第一步，为此我在Net上编写了简单的服务器，在oio plain TCP上编写了简单的客户端。 客户端发送随机文本包，并且必须接收“确认”消息。 请参阅处理程序方法： @Override public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception { ctx.write(“Ack”); ctx.flush(); ByteBuf in = (ByteBuf) msg; StringBuilder sb = new StringBuilder(); try { while (in.isReadable()) { sb.append((char) in.readByte()); } } finally { ReferenceCountUtil.release(msg); } LOG.debug(“Incoming message. ACK was send”); String myaddr = ctx.channel().remoteAddress().toString(); String message = “Message from ” […]
