java - Netty sendBufferSize receiveBufferSize 引导选项

Question

您能否向我解释一下与 bootstrap 一起使用的 sendBufferSize receiveBufferSize 选项背后的想法:

bootstrap.setOption("sendBufferSize", 1048576); 
bootstrap.setOption("receiveBufferSize", 1048576);

我注意到当客户端之间传输大数据时，它们可以提高以下代码的性能:

// encode method in OneToOneEncoder subclass -> 1st client
ChannelBuffer buffer = ChannelBuffers.buffer(capacity);
buffer.writeInt(myData);

// decode method in FrameDecoder subclass -> 2nd client
int myData = buffer.readInt();

谢谢!

Answer 1

这些选项指定 Channel 底层 Java 上的缓冲区大小 Socket实例。What are SO_SNDBUF and SO_RECVBUF 中很好地总结了这些含义。 .
