boolean isTcpNoDelay()
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

remote peer shuts down output. Instead,
ChannelInboundHandler.userEventTriggered(ChannelHandlerContext, Object)
is invoked with a ChannelInputShutdownEvent
object. If false

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
