The Plan (updated January 28, 2006)

Notes

       tcp_low_latency - BOOLEAN
       If set, the TCP stack makes decisions that prefer lower
       latency as opposed to higher throughput.  By default, this
       option is not set meaning that higher throughput is preferred.
       An example of an application where this default should be
       changed would be a Beowulf compute cluster.
       Default: 0

Ideas

 if(setsockopt(sockfd, proto->p_proto, TCP_NODELAY, &one, sizeof(one)) < 0)
 {
   printf("NetPIPE: setsockopt: TCP_NODELAY failed! errno=%d\n", errno);
   exit(556);
 }
