Aha. (As a note, it's always useful to set debug level when you experience problems). > Why am I getting low throughput of IP multicast vs IPoIB UD UDP unicast? It's something in the hardware - it's not handing out completions fast enough, . Try increasing send queue size through IPoIB module parameter.
