title: Is it possible to tell whether an application has disabled Nagle's algorithm?
body: <p>Given a binary application running on linux PC. Is it possible to determine if it disables the Nagle's algorithm.</p>
  
  <p>One way could be to see the output in wireshark and depending on the time differences. Could you please tell me a reliable way of finding it out from the wireshark output?</p>
  
  <p>Is there a more direct way? Can I trace the system call which sets the <code>tcp_nodelay</code> option?</p>
  
  <p>The target application could be a web server, application server, database listener or any other server process.</p>
