UDP Netty setOption，ConnectionlessBootstrap或ChannelConfig

Question

我正在使用Netty 3.6.6 Final，我希望在UDP Netty IO Client实现中设置sendBufferSize和receiveBufferSize选项，ConnectionlessBootstrap setOption（）和ChannelConfig setOption（）之间有什么区别？我应该使用哪两种setOption方法，还是重要？

DatagramChannelFactory datagramChannelFactory = new NioDatagramChannelFactory(Executors.newCachedThreadPool());
ConnectionlessBootstrap connectionlessBootstrap = new ConnectionlessBootstrap(datagramChannelFactory);
connectionlessBootstrap.setPipelineFactory(...);
ChannelFuture channelFuture = connectionlessBootstrap.connect(new InetSocketAddress(host, port));
channelFuture.awaitUninterruptibly();
Channel channel = channelFuture.getChannel();
ChannelConfig channelConfig = channel.getConfig();
// Now, do this:
channelConfig.setOption("sendBufferSize", udpSendBufferSize);
channelConfig.setOption("receiveBufferSize", udpReceiveBufferSize);
// or do this:
connectionlessBootstrap.setOption("sendBufferSize", udpSendBufferSize);
connectionlessBootstrap.setOption("receiveBufferSize", udpReceiveBufferSize);

没关系......通常你会为所有频道使用ChannelConfig per Channel和Bootstrap。
