As you wrote TCP_NODELAY is used to turn off Nagle. As per theory this algo will be running at the sender side and delay acks at the reciever side. If I turn off Nagel at sender side, wont this lead to the silly window syndrome ?? Also is it true that Nagles algo and hence delay acks come into play only if the packet size is small ?? Thanks, Rahul. On Wed, 21 Jul 2004, Thomas Giese wrote: > > Nagle is automatically turned off on a per socket basis if you set the > TCP_NODELAY > socket option on the socket.
