  - isTcpNoDelay
```
boolean isTcpNoDelay()
```
    Gets the StandardSocketOptions.TCP_NODELAY option. Please note that the default value of this option is true unlike the operating system default (false). However, for some buggy platforms, such as Android, that shows erratic behavior with Nagle's algorithm disabled, the default value remains to be false.

SocketChannelConfig setAllowHalfClosure(boolean allowHalfClosure)
```
    Sets whether the channel should not close itself when its remote peer shuts down output to make the connection half-closed. If true the connection is not closed when the remote peer shuts down output. Instead, ChannelInboundHandler.userEventTriggered(ChannelHandlerContext, Object) is invoked with a ChannelInputShutdownEvent object. If false, the connection is closed automatically.

    从接口复制的说明: ChannelConfig
    
    Sets the connect timeout of the channel in milliseconds. If the Channel does not support connect operation, this property is not used at all, and therefore will be ignored.
    
    指定者:
    
    setConnectTimeoutMillis 在接口中 ChannelConfig
    
    参数:
    connectTimeoutMillis - the connect timeout in milliseconds. 0 to disable.

```
    从接口复制的说明: ChannelConfig
    
    Sets the maximum number of messages to read per read loop. If this value is greater than 1, an event loop might attempt to read multiple times to procure multiple messages.

  - setWriteSpinCount
```
SocketChannelConfig setWriteSpinCount(int writeSpinCount)
```
    从接口复制的说明: ChannelConfig
    
    Sets the maximum loop count for a write operation until WritableByteChannel.write(ByteBuffer) returns a non-zero value. It is similar to what a spin lock is used for in concurrency programming. It improves memory utilization and write throughput depending on the platform that JVM runs on. The default value is 16.
    
    指定者:
    
    setWriteSpinCount 在接口中 ChannelConfig
  - setAllocator
```
SocketChannelConfig setAllocator(ByteBufAllocator allocator)
```
    从接口复制的说明: ChannelConfig
