Explanation / Answer

public static void main(String... args) throws IOException, InterruptedException { ServerSocketChannel ssc = ServerSocketChannel.open(); ssc.bind(new InetSocketAddress(0)); // open on a random port InetSocketAddress remote = new InetSocketAddress("localhost", ssc.socket().getLocalPort()); SocketChannel sc = SocketChannel.open(remote); configure(sc); SocketChannel accept = ssc.accept(); configure(accept); ByteBuffer bb = ByteBuffer.allocateDirect(16 * 1024 * 1024); // write as much as you can while (sc.write(bb) > 0) Thread.sleep(1); System.out.println("The socket write wrote " + bb.position() + " bytes."); } private static void configure(SocketChannel socketChannel) throws IOException { socketChannel.configureBlocking(false); socketChannel.socket().setSendBufferSize(8); socketChannel.socket().setReceiveBufferSize(8); }
