IMO netperf reporting is actually not too informative without stats settings. Try running with e.g. -i 10,2 -I 99,5 - you might discover that your numbers are only accurate within 30% > Note that the results below show improvement only for TX so we see an end to > end packet loss. Hmm, as long as packet drops increase, BW improvements in UDP don't sound too convincing, do they? You can get infinite BW at 100% drop ... > Improving the receiver (NAPI) will reduce the packet loss. Needs testing with NAPI patch then? -- MST _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
