However, since TCP Window scaling is enabled by default, it is my understanding that the SO_RCVBUF has to be set before the listen() call is invoked. The .tac file passes the TCPServer object to application/service framework, which in turn calls the listener. So I am wondering if I have to derive a subclass of TCPServer and somehow set the SO_RCVBUF value before the application framework invokes listen(); i.e.
drill down to the Port
object where it calls createInternetSocket()?<br></div></blockquote><br></div><div>You'd need to actually subclass tcp.Server, an implementation mechanism that we would really like to deprecate :).</div><div><br></div><div>Really, the right way to do this is to contribute a fix to the ticket I linked, and do it directly next to the listen() call within Twisted :).</div><div><br></div><div>-glyph</div><div><br></div></div></div><br><br> </div> </div> </div></body></html>
