Is it interupt per packet? From my experience, you may find interesting results varying tx interupt mitigation parameters in addition to the ring parameters. Unfortunately when you do that, optimal parameters also depends on packet size. so what may work for 64B, wont work well for 1400B. cheers, jamal _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
