[hpsdr] Gigabit 1000T speed on Metis

[Máximo EA1DDO_HK1H]

Hi all,

I found this;  http://www.psc.edu/networking/projects/tcptune/OStune/winxp/winxp_stepbystep.html

If I set those settings, Is it better?

Thank you

    It is in the application code using the setsockopt call, not
    something you can configure.  I had to do the same for my latest Qt
    based client/server code so it could run on Windows.

    

    An example:

    

        int v=4096; // size of receive buffer

       
::setsockopt(udpSocket->socketDescriptor(),SOL_SOCKET,SO_RCVBUF,(char*)&v,sizeof(v));

        Hi Hermann, 

        

        You said; "e.g., on Win7 I had to increase the socket's buffer
        size to minimize packet losses from Metis."

        

        Can you explain how to do that?

        On XP?

        

        Danke schon.

          Hi,

          

          I have 4 receivers on one Mercury card on my cuSDR running at
          100T - no problem at all. I've made the observation that the
          OS socket implementation makes the difference, e.g., on Win7 I
          had to increase the socket's buffer size to minimize packet
          losses from Metis.
