RE: [ECOS] FreeBSD Stack/ Throughput over TCP/IP

["Richard Rauch" <Richard dot Rauch at vipa dot de>]

thanks for your info, but we already turning off nagle with following code

int CRFC1006SvrLine::Nagle(SOCKET Socket, bool bMode)
{
   _ASSERTE(Socket != INVALID_SOCKET);
   int iPar = bMode ? -1 : 0;
   int iError = setsockopt(Socket,      // socket
                           IPPROTO_TCP,   // level
                           TCP_NODELAY,   // optname
                           (char*)&iPar, // optval
                           sizeof(iPar)  // size
                           );
}

If your sending small size packets? If so you must
turn nagle off, it might be limiting your throughput.
