title: Disable TCP Delayed ACKs
body: <p>I have an application that receives relatively sparse traffic over TCP with no application-level responses.  I believe the TCP stack is sending delayed ACKs (based on glancing at a network packet capture).  What is the recommended way to disable delayed-ACK in the network stack for a single socket?  I've looked at <code>TCP_QUICKACK</code>, but it seems that the stack will change it under my feet anyways.</p>
  
  <p>This is running on a Linux 2.6 kernel, and I am not worried about portability.</p>
