Confusion about multiple connections

Since Nagel has been closed as @manzhizhen said, the 40ms delay should not exist, why do we still need this feature

Line 69 in d42b93d

bootstrap.setOption("tcpNoDelay", true);

Generally, nagle cause a client spent 200ms delay to send data to a server.
And delay ACK cause a server spent 40ms delay to ack client's request data, then following packets will be blocked at least 40ms.
BTW, sometimes TCP Retransmission cause 200ms and then double it in next time.
