** Description changed: A web-enabled home automation controller I'm using advertises a window size of 1 byte during the connection three-way handshake. When a web browser tries to send the initial GET request, there is a several second delay before the GET is sent to the controller. Breaking up the GET into several packets (the first one only a single byte containing the G in GET) gets rid of the delay. I've wound up putting a lot of additional information, including wireshark traces and a little proxy that works around the problem, at http://mvlug.org/JoePfeiffer/SlowGetWithSmartLinc ProblemType: Bug Architecture: i386 DistroRelease: Ubuntu 9.04 HibernationDevice: RESUME=UUID=507643a7-7b89-4f78-8011-cc227d204c65 MachineType: SAMSUNG ELECTRONICS CO., LTD.
