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.<br>
<br>
An example:<br>
<br>
int v=4096; // size of receive buffer<br>
::setsockopt(udpSocket->socketDescriptor(),SOL_SOCKET,SO_RCVBUF,(char*)&v,sizeof(v));<br>

Hi Hermann, <br>
<br>
You said; "e.g., on Win7 I had to increase the socket's buffer
size to minimize packet losses from Metis."<br>
<br>
Can you explain how to do that?<br>
On XP?<br>
<br>
Danke schon.<br>

Hi,<br>
<br>
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.<br>
