Note that my associations are all TCP-style SOCK_DGRAM associations, and not UDP-style SOCK_SEQPACKET associations. As such, each association has its own socket - rather than all the associations sharing a single socket - and thus, to my understanding, the parameters in question will have no effect (as my testing has shown). > You're correct, if you're using TCP style associations, the above policies won't change much. Such consistent throughput sharing though still seems odd. You don't have any traffic shaping or policing implimented on your network devices do you? Either on your sending or receiving system? tc qdisc show would be able to tell you. Such low throughput on a 10G interface seems like it could not be much other than that. Are you seeing any droped frames in /proc/net/sctp/snmp or in /proc/net/snmp[6]?
